44
- note: NEWS format changed, see 01012011 meta entry below
45
- changed: do not use deprecated jack_client_new()
46
- changed: simplified signal handling for not-so-POSIX
47
platforms
48
- fixed: seeks with -klg did not work
49
- fixed: bug in int-float conversions
50
- fixed: some false DBC warnings removed
51

52
- fixed: bug in signal handling caused rubyecasound scripts
53
to fail (e.g. ecasound's own stresstest.rb)
54
- fixed: at end of playback, properly wait until all buffered
55
samples have been played out to ALSA devices
56
- fixed: bug with live seeks and -z:db buffering; caused
57
problems to e.g. JACK transport slaving and
58
live seeks (repositioning without stopping transport)
59
01012011 meta: notes on provided change information in this file
60
- the release entries will be shorter from now on, only
61
listing the affected features (e.g. which objects),
62
and type of change (addition, change, bugfix)
63
- see RELNOTES and git commit history for a more detailed
64
description
65
- author tags will no longer be used, [foobar] used to
66
indicate the author of the change, unless it was from
67
someone from the main author(s); README still lists
68
all the developer tags used; instead git history
69
shows who did what
70
19082010 (v2.7.2) -** stable release **-
71
- added: manual gate (-gm); see ecasound(1) man page
72
- changed: liboil now enabled by default if the library
73
development files are available when running
74
configure
75
- fixed: bug with 'resample' objects and early seeks (e.g.
76
with '-y' offsets); reported by Artur
77
- fixed: bugs in kvutils that broke some old/non-glibc
78
builds (e.g. cygwin); bug reported by Al Oomens
79

82
- note: key changes are described in more detail at:
83
http://eca.cx/relnotes/ecasound_v2_7_1_relnotes.txt
84
- fixed: glitches in ALSA capture/playback with some sound
85
hardware/configurations, and using alsa-lib
86
older than 1.0.15; related to deprecated ALSA API
87
function snd_pcm_sw_params_set_xfer_align()
88
- fixed: bug in removing audio objects when disk double
89
buffering is used (-z:db); could cause a segfault
90
in some scenarios (e.g. with ecasignalview)
91
- fixed: interactive mode; c-selected segfauls if issued
92
with no chainsetup selected
93
- fixed: build errors when no liblo is available
94
- fixed: interactive-mode; cs-setpos, cs-rewind and cs-forward
95
did not work if chainsetup was connected, and no
96
chains (or an invalid chain) was selected; bug
97
reported by Joel Roth
98
- fixed: ecalength choked filenames with whitespace; patch
99
from FUJI project

101
17102009 (v2.7.0) -** stable release **-
102
- note: key changes are described in more detail at:
103
http://eca.cx/relnotes/ecasound_v2_7_0_relnotes.txt
104
- added: new exit code of '4' to ecasound; see entry below
105
about signal handling changes and ecasound(1) for
106
more details
107
- added: -eadb chainop, like -ea/-eac, but gain given in dB;
108
documented in ecasound(1)
109
- added: -chorder chainop; see ecasound(1)
110
- added: optional inner loop optimizations using liboil;
111
enable with '--enable-liboil'
112
- added: OSC support added, see ecasound(1) and
113
Documentation/ecasound_osc_interface.txt; sffeat:2541462
114
- added: in ncurses mode, honor COLUMNS environment variable
115
- added: configure - added '--with-extra-cppflags' and
116
'--with-extra-libs' options
117
- added: new 'cop-get' command; see ecasound-iam(1) [alinson]
118
- changed: ecasound now defines "-D_XOPEN_SOURCE=500" for
119
all builds, expressing that the codebase expects
120
the build environment be compatible with the Single
121
UNIX Spec v2 (1998); thanks to Jussi Laako for
122
reminding about this
123
- changed: yet another change to signal handling in ecasound;
124
now two level response to signals is supported in
125
all stages of process termination -> first starting
126
normal cleanup and exit procudere, and with
127
second signal terminate immediately; see ecasound(1)
128
for the full story (new 'SIGNALS' section)
129
- changed: dropped "-funroll-loops" from the set of default
130
compiler options
131
- changed: comment out many entries in the global installed
132
'ecasoundrc' file (entries are redundant as the same
133
defaults are already set in the program binaries)
134
- changed: optimized inner loops in core chain routing and
135
mixdown functions (with liboil if available)
136
- changed: optimized inner loops of -ea, -eadb, -eac, and -epp
137
- changed: dropped tracking of 'clipped samples' from -ev as
138
the results were of little use (and misleading)
139
- changed: '-ev' status output
140
- changed: cosmetic changes to the default ncurses trace output;
141
reduced number of subsystem-level trace messages
142
- changed: the name for default chainsetup created from command
143
line is now "untitled-chainsetup"
144
- changed: do not automatically connect chainsetups loaded
145
with '-s'
146
- fixed: mp3 output was broken with lame 3.98 (and newer);
147
the default lame parameters have now been updated
148
and have been tested with lame 3.96, 3.97 and with
149
the latest 3.98.2
150
- fixed: bad audio with 'resample' object, non-integer sampling
151
rate change ratios and output to JACK; ecasound did
152
emit warning about this, but did not raise a fatal
153
error; now the underlying problem is fixed and now
154
'resample' and 'jack' objects maybe safely used
155
together
156
- fixed: minor bug in ecamonitor; "cop-status" was used with
157
multiple chains selected
158
- fixed: don't use '--ignore-fail-on-non-empty' rmdir option
159
as it is not available on many platforms (e.g. OS X)
160
and this breaks the uninstall target; sfbug:2772628
161
- fixed: bug in ecasound frontend parser for '-E' option that
162
broken passing arguments containing the substring
163
"-E"; introduced in 2.5.2 release
164
- fixed: stale audio was written to JACK output ports in case
165
of multiple streams, connected to different JACK ports,
166
reaching end-of-stream at different times [jedahu]
167
08022009 (v2.6.0) -** stable release **-
168
- note: key changes are described in more detail at:
169
http://eca.cx/relnotes/ecasound_v2_6_0_relnotes.txt
170
- added: new optional params to 'jack' -> 'jack,clientname,portprefix';
171
replaces old interfaces 'jack_auto', 'jack_generic'
172
and 'jack_alsa'; see ecasound(1) for more details
173
- added: interactive mode - new commands 'jack-connect',
174
'jack-disconnect' and 'jack-list-connections'; see
175
ecasound-iam(1) for details; closes sffeat:2134183
176
- added: 'jack_multi', see ecasound(1); closes sffeat:1415822
177
- added: ecasound options '--server', '--server-tcp-port' and
178
'--no-server'; these replace the misleading old
179
options '--daemon', '--nodaemon' and '--daemon-port',
180
which are now deprecated
181
- added: extended unit tests to cover option parsing, with
182
some initial test cases
183
- added: unit test framework - minor improvements including
184
abilitity to select which cases to run
185
- added: ECI - functions eci_ready() and eci_ready_r() added
186
to ecasoundc.h, and ECA_CONTROL_INTERACE::ready()
187
to the C++ API
188
- changed: deprecated 'jack_auto', 'jack_generic' and
189
'jack_alsa'
190
- changed: numbering of JACK ports created with 'jack' and
191
'jack_generic' starts from "_1" separately for
192
each prefix [dsacre]
193
- changed: deprecated 'ai-wave-edit', 'ao-wave-edit' commands
194
and the 'ext-cmd-wave-editor' ecasoundrc field
195
- changed: emit a 'subsystem' level trace message when
196
engine state changes to finished
197
- changed: interactive mode - minor update to 'status' command
198
output
199
- changed: compile libecasoundc as PIC code to make it possible
200
to use it from shared libraries; fixes problems
201
with e.g. Audio::Ecasound on amd64 architecture ;
202
closes sfbug:2505551
203
- changed: ecasound option -f now accepts empty arguments for
204
sample format, channel count and sampling rate; empty
205
argument states that ecasound can pick a suitable
206
value, either the default value or e.g. the JACK
207
system sampling rate; updated documentation, see
208
ecasound(1)
209
- changed: minor update to ecasound's "--help"
210
- changed: when reading RIFF WAVE files, properly ignore
211
any unknown subchunk types
212
- changed: largefile support (+2GiB files) is now enabled
213
by default and configure uses's default autoconf
214
macro AC_SYS_LARGEFILE to perform the checks;
215
to explicitly disable, use '--disable-largefile';
216
the old '--with-largefile' no longer has any effect
217
- changed: refactored ECI C impl code to get rid of all
218
fixed size buffers from the parser; this makes
219
the implementation more robust, reduces memory
220
usage and provides a small speed-up to most ECI
221
apps; closes sfbug:1412409
222
- fixed: do not limit max-gain reported by '-ev' to [1,max]
223
value range
224
- fixed: avoid denormal numbers in '-ete' (leads to unusually
225
high CPU load)
226
- fixed: 'dump-cop-value' did not work as documented
227
- fixed: ECI - signal an error (e.g. eci_error() returns true)
228
if connection is lost to engine process (sync lost
229
or an other error)
230
- fixed: ecasignalview - exit if engine reports an error
231
during operation
232
- fixed: interactive mode - loop devices saved with incorrect
233
syntax, affects cs-save, cs-save-as and cs-edit ; see
234
http://eca.cx/ecasound-list/2009/01/0058.html
235
- fixed: problems when seeking back to start with setups using
236
loop devices; closes sfbug:2527049
237
- fixed: segfault if using a tone generator input with a fixed
238
lenght, and a seek past the end of stream was performed
239
- fixed: aac/ogg/mikmod/mid inputs - once object reached state
240
'finished' (all samples played), it cannot be played
241
again by reconnecting the chainsetup
242
- fixed: combination of '--server' and '-C' (disable interactive
243
mode) had a bug that prevented processing of commands
244
received over the server socket while the engine
245
was running the batchmode
246
- fixed: a nasty bug in 'playat' implementation causing audible
247
artifacts ; see
248
http://eca.cx/ecasound-list/2009/01/0089.html
249
- fixed: sndfile and audiofile backends - emit a warning if
250
a seek fails (e.g. when seeking beyond current
251
end-of-file for output objects)
252
- fixed: various improvements and fixes related to using
253
non-seekable audio objects (especially interactive
254
use); in most cases this means graceful recovery
255
from failed seek attempts, and correct reporting of
256
the objects actual current position
257
- fixed: error is emitted if trying to use 'select' with
258
objects that do not support seeking
259
- fixed: bugs with passing 'auto' as the 2nd parameter of
260
'resample'
261
- fixed: bug with seeking resampled audio objects
262
- fixed: bug in combined use of 'audioloop' and 'resample'
263
- fixed: catch and warn about various errors cases when
264
given incorrect or missing params to audio
265
types: typeselect, resample, reverse, playat,
266
audioloop, select
267
24082008 (v2.5.2) -** stable release **-
268
- more verbose description of change available at:
269
http://eca.cx/relnotes/ecasound_v2_5_2_relnotes.txt
270
- fixed: bug in channel routing of LADSPA plugins that have
271
more audio output ports than input ports
272
21082008 (v2.5.1) -** stable release **-
273
- more verbose description of change available at:
274
http://eca.cx/relnotes/ecasound_v2_5_1_relnotes.txt
275
- fixed: a last minute change in 2.5.0 that caused build errors
276
with gcc-4.3.1 if ALSA support is disabled
277
- fixed: a change in 2.5.0 how process cleanup is initiated from
278
the signal handler caused severe problems on some
279
systems when ecasound was interrupted with e.g.
280
ctrl-c/SIGINT; worst case was a crashed X session which
281
is of course really, really bad
282
- fixed: a bug in registering LADSPA plugins; on some systems
283
not all found plugins were registered properly to
284
ecasound's object maps causing some plugins to be
285
unusable; errors
286
16082008 (v2.5.0) -** stable release **-
287
- more verbose description of change available at:
288
http://eca.cx/relnotes/ecasound_v2_5_0_relnotes.txt
289
- notice: slightly modified the version numbering scheme -
290
minor version is incremented whenever non-trivial
291
new features are added
292
- notice: verified to compile with minimal warnings with
293
gcc-4.3.1
294
- edi-entries: edi-40 closed (Update to error and warning
295
reporting mechanisms), edi-38 closed (see
296
edi-7 partially implemented
297
- added: ecasound.el: added missing ECI commands cs-option,
298
cs-set-length, cs-set-position-samples, ai-get-length,
299
ai-set-position, and ai-set-position-samples [dto,
300
mlang]
301
- added: tone generator input; '-i:tone,sine,440,10.3' will
302
create a 440Hz sine tone with duration of 10.3 seconds;
303
this input type will be especially useful for reproducing
304
bugs in complicated chainsetups, without the need to
305
exchange complete session data (which usually are composed
306
of large amounts of audio data)
307
- added: audio looper object; "-i:audioloop,foo.wav" will play
308
'foo.wav' and loop it indefinitely
309
- added: audio selector object; "-i:select,5,15.2,foo.wav" will
310
play 15.2sec of "foo.wav", starting at position 5sec;
311
relates to (edi-7)
312
- added: audio play-at object; "-i:playat,5,foo.wav" will
313
start playing "foo.wav" after position reaches 5sec
314
- added: EWF files; ability to specify positions in time in
315
sample frames; "2.0" is interpreted as 2.0secs while
316
"88200sa" is interpreted as 88200 samples
317
- added: 'reopen-count' parameter to threshold gate (-ge);
318
for instance when recording vinyl/tapes, this allows
319
to automatically restart recording when a new track
320
is started [andrewl]
321
- added: ecasound frontend option '-E "cmds"' that allows
322
to run a set of interactive mode commands at
323
startup; see ecasound(1) for details; closes (edi-38)
324
- added: a notice is printed in case audio object's audio
325
format parameters differ from the chainsetup's default
326
values (audio object's own params always override
327
any value set by e.g. '-f:...').
328
- changed: most of the EWF support (Ecasound Wave Files, .ewf)
329
has been rewritten in this version; numerous bugs
330
are fixed
331
- changed: eaim - commands 'cop-add' and 'ctrl-add' now allow
332
an alternate syntax: both "-<id_string>:par1,...,parN"
333
and "<id_string>:par1,...,parN" are now accepted
334
- changed: ability to write to EWF file is now marked as
335
a deprecated feature which will be removed in
336
a later release
337
- changed: mechanism to terminate forked child processes;
338
properly wait for process termination in all
339
circumstances (previously there were some
340
unhandled corner cases)
341
- changed: major updates to the examples.html page (available
342
also at http://eca.cx/examples )
343
- changed: refactored logic for propagating seek events
344
across chainsetups; warnings are now issued if
345
one tries to seek objects that do not supports
346
seeking; similarly warning is issued if a given
347
audio object type doesn't support sample accurate
348
seeks (for example mp3 inputs have this limitation)
349
- changed: updated ecasound(1) man page description of '-klg'
350
- changed: separate global (-d, -R, ...) and ecasound frontend
351
specific (-c, --daemon, -s, ...) options in
352
ecasound(1) man page
353
- changed: changes to "cs-status" (aka "status", "st")
354
output formatting; now more information about
355
selected and connected setups is printed out
356
- changed: minor changes to the information printed out when
357
open audio input/outputs
358
- changed: pipes, sockets and device nodes in LADSPA plugin
359
directories are skipped (previously hidden files
360
were already skipped)
361
- changed: loop device identifier was changed from an integer
362
to a generic string; both "-i:loop,1" and
363
"-i:loop,myloop" are now valid
364
- fixed: incorrect usage of the Python C API, which leads to
365
segfaults when pyecasound is used under python2.5;
366
fixes Debian bug #468965
367
- fixed: bugs in ewf-looping code
368
- fixed: avoid terminating processing when invalid parameters are
369
passed to channel copy (chcopy/erc), mix (chmix/erm) and
370
move (chmove) chainops
371
- fixed: eaim - buffering mode was sometimes incorrectly
372
reported in 'cs-status' output (-B:auto instead of
373
the actual set buffering mode) output; bug reported by
374
Jan Weil
375
- fixed: compilation warnings from GCC-4.3; fixes Debian bug
376
#454890, patch from Cyril Brulebois
377
- fixed: bug in passing multiple arguments to 'typeselect',
378
'resample', and 'resample' objects
379
- fixed: with some glibc versions (tested with 2.3.6.ds1-13etch5),
380
ecasound did not fully clean up all threads when
381
it received a signal and terminated; the bug showed
382
up as a stuck thread, with backtrace pointing to
383
pthread_onexit_process()
384
- fixed: compilation issue on Mac OS X 10.5 [grobian]
385
- fixed: bug in saving control state with 'cs-save' or
386
'cs-save-as'; triggered if controller was followed
387
by more chainops on the same chain
388
- fixed: bugs with preserving state across seeks with
389
many controller objects (-kl, -kl2 and -kos)
390
- fixed: a bug in ecasound user's guide w.r.t. usage of
391
loop devices
392
- fixed: sloppy parsing of "-i:loop" and "-o:loop" arguments
393
leading to confusing error messages when invalid input/output
394
objects, containing the substring "loop" were passed
395
as arguments to "-i" and "-o"
396
14082007 (v2.4.6.1) -** stable release **-
397
- fixed: extra debugging, printed to stderr, for resource file
398
values was accidentally left enabled in the 2.4.6 release
399
14082007 (v2.4.6) -** stable release **-
400
- more verbose description of change available at:
401
http://eca.cx/relnotes/ecasound_v2_4_6_relnotes.txt
402
- added: new option '-R:path-to-resource-file' to use a custom
403
resource file and disable querying of global and user
404
resource files; as a special case, by setting this
405
to '/dev/null', one disable all access to resource
406
files; requested by Klaus Schulz and Keith Creasy
407
- added: eiam - new command 'resource-file'; see ecasoundrc(5)
408
man page; related to previous item
409
- changed: license of rubyecasound, the Ruby ECI API
410
implementation, has been changed from GPL to LGPL
411
- fixed: build errors caused by missing #includes, reported
412
by GCC 4.3; bug report from Debian, bug #417178
413
- fixed: rounding errors with small buffersizes caused time crop
414
gate (-gc) to function incorrectly; reported by Joe
415
Planisky
416
- fixed: force localization of decimal numbers to "POSIX" (i.e.
417
use period as the separator) to avoid bugs with
418
e.g. LADSPA plugins that call setlocale and break
419
the ecasound option parser; for instance all swh-plugins
420
call setlocale; reported by R�mi Rouaud
421
- fixed: printing chain operator (e.g. the '-ev' operator) status
422
at end of sessions was broken in 2.4.5; reported by
423
Julien Claassen
424
- fixed: bugs that led to infinitely running chainsetups when
425
loop input/outputs were used; reported by Aaron Heller
426
and Etienne Deleflie

428
the Ecasound Programmer's and User's Guides; patch
429
from Junichi Uekawa

- more verbose description of change available at:
434
http://eca.cx/relnotes/ecasound_v2_4_5_relnotes.txt
435
- added: ability to compile without a readline library (will
436
disable the curses based console user-interface)
437
- added: if libsndfile is found and supports flac (sndfile
438
1.0.12 or newer), it will be used as the default
439
handler for flac files; use of sndfile makes random
440
access for flac files possible (for example seeking
441
in interactive mode)
442
- added: section on 'RETURN VALUES' to ecasound(1) man page
443
- added: ecasound-iam(1) - added documentation for error
444
return values for 'run', 'start' and 'cs-connect'
445
- added: ECASOUND_LOGFILE and ECASOUND_LOGLEVEL environment
446
variables; see ecasound(1) for documentation
447
- added: more detailed description of debug levels that
448
can be set with 'd' to ecasound(1) manpage
449
- added: examples section to ecasound(1), which points to

453
and '-chcopy' for '-erc'
454
- added: ability to protect EOS arguments, like filenames, with
455
double quotes, closes bug #1456510; see also the related
456
BUGS entry about handling commas in filenames, and
457
updated documentation in ecasound(1), ecasond-iam(1)
458
and the User's Guide
459
- removed: readline-4.0 subdir from the dist package; system
460
readline library is now the only build option
461
- changed: ecasoundrc - added "-f" to the default flac
462
output exec command (although now libsndfile's
463
flac support is the default)
464
- changed: improved libsndfile integration, any libsndfile
465
supported file format can be used as output for
466
'sndfile,foo.ext' (format selected based on filename
467
extension)
468
- changed: eiam - default int-log-history length set to zero
469
- changed: updated config.guess and config.sub to more recent
470
versions (timestamp 2006-07-02)
471
- changed: updated the documentation for 'ai-select/ao-select',
472
it is no longer required that input/outputs have
473
a unique name within one chainsetup; problem reported
474
by Kurt Konolige
475
- changed: replaced the ECI C implementation's (libecasoundc)
476
engine cleanup mechanism with a much more robust one
477
- changed: the engine will now refuse to start if a start offset
478
is given with '-y:secs' for an object not supporting
479
seeking; this has been a very common source of
480
end-user confusion
481
- fixed: segfault when removing loop devices with a[io]-remove,
482
reported by Pedro Antonio Fructuoso Merino
483
- fixed: incorrect headers in created flac files (not related
484
to sndfile/flac); fix can possibly affect other file
485
formats handled by external apps (aac, midi, mikmod,
486
mp3 and ogg files), problem reported by Florian Ladstaedter
487
- fixed: errors during batch processing (running out of file
488
space, etc) were not reported as a non-zero process
489
return value, problem reported by Zrajm Akfohg
490
- fixed: possible segfaults with ctrl-select, ctrlp-select

499
to segfaults when breaking a batch run with ctrl-c
500
- fixed: bug causing audible glitching when seeking with
501
chainsetups containing loop devices [pfructuoso]
502
- fixed: "rw 0" caused the engine to skip ahead multiple
503
seconds (reported by Kurt Konolige)
504
- fixed: segfaults from invalid params to -f option, for
505
example "-f:16" or "-f:16,2", reported by peppo on
506
#lad at freenode.org
507
- fixed: a severe string termination bug in libecasoundc
508
that led to garbled output from ECI commands
509
returning lists of strings, reported by Brad Bowman,
510
Joel Roth and Stuart Allie
511

- fixed: ewf-debugging output was left enabled in 2.4.2 release
570
- fixed: bug in detecting finished-state with .ewf files when
571
used with -z:db mode enabled -> caused flood of underrun
572
warnings with multi .ewf file sessions
573
- fixed: externally terminating, e.g. via JACK transport system,
574
a batch chainsetup would cause a segfault

672
- added: support for having commas in arguments by escaping
673
them with a backslash (example: "ai-add foo\,bar.wav")

so that all lines fit into 74 columns; does not affect
676
wellformed output mode nor stderr output (-D)
677
- added: new section about handling commas in filenames to
678
Ecasound User's Guide
679
- added: eiam - new 'int-log-history' command to query
680
recent log messages sent by libecasound; this is a very
681
useful tool for debugging ECI scripts and apps
682
- added: eiam - new 'int-set-log-history-length' command to set
683
log history length; default to 5 items
684

685
the internal resampler even though support for
686
libsamplerate is enabled at build time
687

688
the old average mixing is still the default; see
689
ecasound(1)

691
- changed: more helpful messages to explain why a chainsetup
692
cannot be connected to the engine
693
- changed: EIAM - when returning a list of strings, all commas
694
in list elements are now escaped with backslashes;
695
this is done to avoid ambiguity in parsing
696
- changed: new default debug level of 271
697
- changed: new optimized message queue implementation used in
698
communication between the engine and the interface
699

where ecasound could block in real-time critical
701
code-paths
702
- changed: better error message if unable to load LADSPA plugin
703
with -el/-eli
704
- changed: removed hard upper-limit for -ei scale-factor,

715
bufsize or srate on the fly, but at least it now fails
716
gracefully
717
- fixed: always pass filename (%f) as one parameter to the
718
external apps; fixes bug present in 2.3.4 and 2.3.5
719
releases which broke handling spaces in filenames;
720
affected all file formats handled via external tools
721
(ogg/mp3/flac/m4a/...); also a separate bug in handling
722
spaces in ogg output filenames was fixed
723
- fixed: occasional bugs with rubyecasound in handling the
724
EIAM 'quit' command; this also fixes the errors in
725
running 'make check' in ecasound/rubyecasound
726
- fixed: serious bugs in resampling between 96000 and 44100/48000
727
rates when using libsamplerate; upgraded Ecasound to use
728
the libsamplerate 'full API'
729
- fixed: options "-b:", "-b" and "-b:0" caused a segfault
730
- fixed: aac/m4a encoder was not stopped properly after
731
processing was finished

778
to 4-byte ALSA formats S24_LE/_BE; now mapped
779

803
- fixed: signal handling bugs in ecasignalview and ECI C
804
impl [mewe]

- fixed: bug in ecasound(1) caused man to not show the
806
last three pages
807
- fixed: bug in the daemon-mode (NetECI) protocol parser
808
that caused parsing long (over 32 chars) commands
809
to fail
810
- fixed: 'libecasound-config --libs' did not list all
811
external libraries used
812
- fixed: assign default param-names to effect presets
813
- fixed: preset parameters were not saved by 'cs-save' and
814
'cs-save-as'
815
06122003 (v2.3.2) -** stable release **-
816
- edi-entries: edi-33 closed

- added: support for libsndfile; enabled if libsndfile is
818
detected succesfully by configure; can be disabled
819
with --disable-sndfile

821
'sndfile' and 'mikmod'; see ecasound(1) for more
822
details

824
- added: initial Ruby ECI impl added; see rubyecasound/README
825
for details [janweil]

827
yes if ruby interpreter found on the system
828
- added: resampling examples to Documentation/examples.html
829
- changed: increased default buffer sizes for 'rtnull' objects
830
to avoid too many xrun warnings; warnings are also
831
no longer printed to stderr - instead a summary
832
is printed at the end of the session if any xruns
833
have occured
834
- changed: Ecasound PDF docs (user's, programmer's and ECI
835
guides) are now generated using AE fonts; the PDFs
836
can now be read with readers like xpdf and
837
probably look better in others [janweil]
838
- fixed: pyecasound/test1_stresstest.py was not included in
839
the dist package
840
- fixed: libaudiofile - input file audio parameters
841
parsed incorrectly
842
- fixed: -x option - truncate outputs - was not working
843

- fixed: typo in libecasoundc-config usage [koraq]
850
- fixed: bugs with resample that caused audible artifacts
851
with certain srcrate-dstrate combinations
852
19112003 (v2.3.1) -** stable release **-
853
- added: --disable-effects configure option; build ecasound
854
without effect and controller components
855
- changed: libtool is setup to only create object files for
856
static linkage; you can revert to the old behaviour
857
with the --enable-shared configure option
858
- changed: ecasound.el updated to 0.8.3, lots of small
859
changes, see ecasound.el for details [mlang]
860
- changed: pyecasound - due to bugs found in the native python
861
impl, the C ECI impl is again set as the default;
862
can be overridden using --enable-pyecasound=IMPL
863
- changed: pyecasound - the native python impl (ecacontrol.py)
864
now returns an error if communication with the
865
ecasound process times out
866
- changed: html versions of programmer's, user's and ECI
867
developer's guide are generated with Hevea instead
868
of latex2html [juekawa]
869
- changed: updated config.guess and config.sub to more recent
870

875
OSS driver
876
- fixed: compilation against alsa-lib-1.0.x
877
- fixed: default ratio value incorrectly set for -eca; does
878
not affect presets using -eca [remon]
879
29082003 (v2.3.0) -** stable release **-
880
- edi-entries: edi-4, edi-19 and edi-35 frozen, edi-38 added
881
and frozen immediately, edi-39 added; frozen is
882
a new status for items that probably won't be
883
ever implemented
884
- note: verified to compile ok with gcc-3.3
885
- note: verified to work with python-2.3
886
- added: eaim - command 'engine-launch' to inialize engine
887
without starting actual processing, and 'engine-halt'
888
for halting it without disconnecting; useful with
889
JACK transport functions
890
- added: separate AUTHORS file; also added to the website
891
- added: -d, -dd and -d command-line options, see ecasound(1)
892
- added: recording offset parameter -z:multitrack,offset option
893
- changed: to avoid resampling faults, upper limit of 2000%
894
set for pitchshifter's (-ei) shift-% arg; note! high
895
values of shift-% can still cause crashes if using
896
libsamplerate
897
- changed: if available, use pthread API for setting scheduler
898
params; might improve real-time reliability on
899
rh9.0 machines and others that have NPTL
900
- changed: pyecasound - redefined configure option
901
--enable-pyecasound=IMPL where 'IMPL' is either
902
'c' or 'python'; --disable-pyecasound disables
903
them both
904
- changed: pyecasound - if ecasound's build prefix does not
905
match the python prefix, /usr or /usr/local,
906
pyecasound will be disabled; you can override
907
this by specifying the python module directory
908
explicitly with the --with-python-modules=DIR
909
option
910
- changed: JACK transport support code to the new API
911
introduced in 0.76.1 and newer
912
- changed: ecasound.spec; added 'AUTHORS'
913

914
'notransport', 'send', 'recv' and 'sendrecv'
915
- changed: major updates to README file
916
- changed: improved check for aRts; now verifies that linking
917
against libartcs actually works before enabling
918
the arts plugin
919
- fixed: use of the JACK transport API was never actually
920
enabled in 2.2.3
921
- fixed: .aiff/.snd/.au input/output was not working at all
922
due to a typo in source code
923
- fixed: a chain with a short input file could cause a nasty
924
feedback loop if processed with certain effects
925
and mixed with audio from other chains
926
- fixed: ewf length and offset errors with sample rates
927
different from default (usually 44.1kHz)
928
- fixed: chainsetup samplerate incorrectly set with some
929
configurations; caused problems with -t:xxx and
930
other functions related to chainsetup level position
931
and length
932
- fixed: serious bug in mixing down multiple chains with
933
different number of channels to one output; audio
934
from previous mixdown rounds leaked to unused
935
source channels
936
- fixed: some chainsetup parsing errors were totally ignored
937
and not reported to the user
938
- fixed: eiam - output of map-* commands was broken in
939
certain locales (for example "fi_FI")
940
- fixed: without at least one '-Md' or one '-km' option
941
specified, MIDI-services did not work
942
- fixed: pulse gate timing inaccuracy (-eemp); also affected
943
the bpm pulse gate (-eemb) and thus the metronome
944
preset (-pn:metronome)
945
- fixed: a 'setpos' on a not yet connected chainsetup would
946
cause seeks to the wrong position for objects with
947
non-default samplerates
948
- fixed: pay regard to -z:multitrack and -z:nomultitrack when
949
saving chainsetups to .ecs files
950
27042003 (v2.2.3) -** stable release **-
951
- added: support for both -0.64 and 0.65- JACK versions;
952
transport functionality is only enabled with the
953
newer versions
954
- added: automatic query of child object sample rate by
955
giving 'auto' as 2nd arg to resample object
956
- changed: by default python version of ECI is used; the C
957
python module for ECI, pyecasound, is only compiled
958
if --enable-pyecasound is specified
959
- changed: jack_auto,dstclient input/output object now
960
automatically connects to matching ports of JACK
961
dstclient (no longer requires dstclient to have
962
in_X/out_X port names)
963
- fixed: yet another fix for creating temporary files in
964
ecanormalize and ecafixdc; now both LOGNAME and USER
965
are checked for a valid user name
966
- fixed: prefer usleep over nanosleep on cygwin; avoids
967
the excessive-cpu-usage problem
968
- fixed: work-around for a bug in the pcm plugin of ALSA 0.9.1
969
and earlier that caused recording/playback to
970
stop to an audio i/o error
971
- fixed: inconsistencies in how configure --disable/enable-feat
972
options were handled
973
- fixed: if pyecasound was disabled at build time, make
974
install target failed in ecasound/pyecasound
975
18032003 (v2.2.2) -** stable release **-
976

986
- added: new tutorials page added to documentation;
987
see Documentation/index.html
988
- changed: ecasound.el updated to 0.8.2, lots of small

991
dmix which have strict period size constraints
992
- fixed: libecasound sample conversion unit test failed when
993
compiled with gcc-2.91.66 on certain platforms
994
- fixed: compile failed on systems that don't have nanosleep()
995
- fixed: subtle bug in -kl and -kl2 (and possibly others)
996
with fade lengths under 1s
997
- fixed: alsa-0.9 - prevent ecasound from prefilling too
998
much data to output devices
999
- fixed: a ':' in LADSPA plugins parameter name confused
1000
ecasound (swh's sc4 is one example)
1001

- added: sane default param hints for chainops: -ec, -etd,
1009
-ete, -etf, -etl, -etm, -etp, -etr and -epp
1010
- added: if configured with JACK-support, ecasound will
1011
fetch the correct bufsize and srate parameters from
1012
the JACK server when connecting a chainsetup with
1013
JACK inputs or outputs
1014
- added: support for Erik de Castro Lopo's libsamplerate
1015
resampling library; used both by the resample
1016
audio i/o object and the pitch shifter chainop (-ei);
1017
enable with --with-libsamplerate
1018
- added: --disable-libsamplerate; don't enable libsamplerate
1019
support even if the library is found during configure
1020
- added: resample-hq audio object type; like resample, but
1021
use the highest available resampling quality;
1022
currently only has an effect if libsamplerate

support is enabled
1024
- added: alternative UNIX signal handling for platforms that
1025
don't provide sigwait() (cygwin is one)
1026
- changed: ecasoundrc - ladspa-plugin-directory can contain

the LADSPA_PATH syntax and ecasoundrc
1030
- changed: rewritten much of the JACK slave-mode code; enables
1031
much faster and reliable transport-sync
1032
- fixed: compiling pyecasound failed on alpha w/ gcc-3.2
1033

1160
first channel
1161
- fixed: LADSPA param descriptions were incorrectly
1162
parsed
1163
- fixed: ecasound ended up in a cpu-intensive loop if

- fixed: unnecessary warnings when adding audio
1207
objects to a chainsetup with no chains
1208
currently selected
1209
- fixed: resample, reverse and typeselect audio objects
1210
types were broken in 2.1dev11
1211
- fixed: removing audio inputs and outputs didn't work
1212
as specified
1213
- fixed: bugs in multitrack-mode operation; processing
1214
would stop once all input objects were
1215
finished
1216
- fixed: pyeca.py - correct handling of 'e' and '-'
1217
return types [jhalttun]
1218

parameter defaults (as used in swh-0.2.8 plugin
1228
set); updated ladspa.h included in the source tree
1229
- changed: rewrite of all user-interface code that's
1230
in the ecasound-x.y.z/ecasound directory
1231
- changed: added chainop and controller parameter
1232
descriptions back to ecasound's command-line
1233
help (--help/-h)
1234

1244
- fixed: libecasound_tester failed on machines without
1245
the LADSPA SDK plugins installed
1246
- fixed: ia-mode - ctrl-d didn't exit as it should; this
1247
broke shell scripts that used pipes to communicate
1248
with ecasound
1249
24062002 (v2.1dev10)
1250
- added: -G:mgrtype,optstring switch for setting
1251
audio object manager level options
1252

1253
ecasound(1) for details
1254
- added: --enable-all-static configure option
1255
- added: --disable-jack configure option; disable JACK
1256
support even if all required libs and headers
1257
are found
1258
- changed: major data structure cleanup in the JACK
1259
plugin
1260
- changed: JACK support is now enabled if 'jack/jack.h'
1261
is found; also --with-jack=PATH still works
1262
- fixed: 'unknown device state' errors with multichannel
1263
soundcards like midiman deltaXX and rme
1264
when starting processing and if -z:intbuf mode
1265
was selected
1266
- fixed: due to changes in autoconf variables, non-atomic
1267
locking was always used instead of atomic locking
1268
in 2.1dev8 and 2.1dev9
1269
- fixed: configure failed if an old (<0.9) ALSA version was
1270
installed even if --disable-alsa was specified
1271
- fixed: loading chainsetup from interactive mode failed
1272
both with cs-load and after cs-edit
1273

1274
--enable-sys-readline failed
1275
- fixed: bugs in the -z:db subsystem caused segfaults
1276
- fixed: problems with -z:db and small files

1278
17052002 (v2.1dev9)
1279
- edi-entries: edi-22
1280
- changed: optimized disk i/o subsystem (-z:db) performance
1281

1282
- fixed: disk i/o subsystem didn't discard all old data
1283
after a seek to a new location
1284
- fixed: installing pyeca.py failed if ecasound was
1285
built outside srcdir
1286
- fixed: timeouts when starting chainsetups with JACK
1287
input/outputs
1288
- fixed: bug in stopping JACK input/outputs; affects
1289
seeking in interactive mode
1290

1291
- edi-entries: edi-13, edi-18, edi-21, edi-22
1292
- added: reverse audio object type; see the ecasound(1)
1293
man page for better documentation
1294
- added: pyecasound - if python version is 2.2 or higher,
1295
pyeca.py sets custom dlopen flags before importing
1296
the actual pyecasound python module; this makes it
1297
possible to access ecasound's plugins (ALSA, JACK,
1298
libaudiofile) from python ECI apps
1299
- added: ecasoundrc - 'default-audio-format'; same syntax
1300
as with the -f option; defaults to s16_le,2,44100,i
1301
- added: edi-18 implemented; engine samplerate is now
1302
set automatically - if object sample rates don't
1303
match, an error is printed
1304
- added: edi-21 implemented; a much improved framework
1305
for handling audio position information is now
1306
in place; -kl, -kl2 and -klg are now position
1307
aware - changing chainsetup position also affects
1308
controller sources
1309
- added: initial implementation of edi-22
1310
- added: support for devfs /dev/sound/dsp devices [karmak]
1311
- added: new debugging system in libecasound; semantics
1312
of -d:xxx debug levels have changed
1313
- added: 'make check' target builds and runs
1314
libecasound/libecasound_tester, which performs
1315
a set of functionality tests
1316

1317
0.4.x and 0.5.x

1329
- changed: programmer's guide updated; added a new chapter
1330
about library organization
1331
- changed: minor user's guide update
1332
- changed: looping with -tl always loops from the start;
1333
-y can't be used for setting the loop start
1334
offset -> ewf-files should be used instead
1335
- changed: s24_le and s24_be sample formats are interpreted
1336
as three-byte values, not as four-byte
1337
24-in-32bits values as before; to access
1338
unpacked 24bit data, use s32_le and s32_be
1339
formats instead
1340
- changed: configure.in cleanup
1341
- changed: the libkvutils binary API has changes so its
1342
version number was changed from 3:0:1 to 3:0:0
1343
(libkvutils.so.3); this interface will be
1344
frozen together with libecasound.so.8
1345
- changed: rewritten rtnull implementation; now imitates
1346
soundcard behaviour much more accurately
1347
- changed: numerous portability improvements to the
1348
autoconf scripts
1349

- changed: ecasound-config renamed to libecasoundX-config
1352
- changed: ecasoundc-config renamed to libecasoundcX-config
1353

1354
incdir/libecasound, similarly libecasoundc headers
1355
to incdir/libecasoundc
1356
- changed: plugin directory name from prefix/lib/ecasound-plugins
1357
to prefix/lib/libecasoundX-plugins, where X is
1358
the library interface number
1359
- fixed: -[io]:alsaplugin,x,y didn't work with latest ALSA
1360
0.9betaX releases
1361
- fixed: serious bug in setting up ALSA 0.9.x buffering params
1362
- fixed: rare bug with sampling rate changes
1363
- fixed: autoconf 2.5x fixes [iondiode]
1364
- fixed: typeselect - opening and closing a typeselect
1365
device multiple times caused a seg.fault
1366
- fixed: some ECI apps dumped core when executing their
1367
first command
1368
- fixed: after mp3/ogg/mikmod/timidity objects had reached
1369
finished state, playback couldn't be started
1370
without doing a disconnect-connect
1371
- fixed: better handling of situations where JACK server
1372
is abruptly shutdown and then restarted
1373
- fixed: sometimes an incorrect length-field was written to
1374
newly created wav-files
1375
- fixed: problems with using ewf-files with doublebuffering
1376
- fixed: loop devices didn't work; resulted in 'explicit
1377
exception' errors
1378
- fixed: configure failed if neither ncurses nor termcap
1379
was installed
1380
- fixed: compile failed if ALSA was not installed (even
1381
with --disable-alsa)
1382
- fixed: if compiled with --with-largefile, when closing
1383
output wav files, riff header block was written
1384
over start of audio data
1385
- fixed: -eemb wasn't working properly, this broke the
1386
'metronome' preset
1387
- fixed: recording offset not set when not in
1388
multitrack mode
1389
- fixed: incorrect parsing of wav headers on big-endian
1390
machines
1391
- fixed: various small fixes to make ecasound compile
1392
with Sun's Workshop6 C5.2 C++ compiler under
1393
64bit Solaris 2.8 (sparc ultra-250)
1394
- fixed: ecasoundrc - ext-cmd-text-editor and
1395
ext-cmd-wave-editor were incorrectly parsed
1396
- fixed: cs-edit didn't preserve chainsetup position
1397
- fixed: cs-edit discarded all changes if the original
1398
chainsetup was connected but the resulting
1399
setup was not valid for reconnection
1400
- fixed: -klg didn't work as documented
1401
16012002 (v2.1dev7)
1402
- edi-entries: edi-12
1403
- added: a watchdog thread that handles thread cleanup;
1404
this is needed especially for audio and chainop
1405
objects which create their own threads (like jack)
1406
- changed: unification of interactive and passive
1407
modes; running ecasound without -c is now
1408
pretty close to "echo run | ecasound -c cmds"
1409
- changed: if an invalid chainsetup is given on the command
1410
line, and -c is given, ecasound will print an
1411
error but will not exit as it did before; you
1412
can continue editing in the ia-mode to check
1413
what was wrong in the setup
1414
- changed: compilation of eca-iamode-parser.cpp is now
1415
significantly faster and takes less resources;
1416
this should fix problems with compiling ecasound
1417
on machines with <256MB of memory
1418
- fixed: audio-manager.h was missing from the dist-package
1419
- fixed: critical bug that prevented writing to
1420
double-buffered non-realtime output objects
1421
- fixed: chainsetups with multiple controller objects of
1422
the same type didn't work in 2.1dev6 [jesse]
1423
- fixed: edi-12 - multichannel, noninterleaved ALSA 0.9 input
1424
and output not working properly
1425
22122001 (v2.1dev6)
1426
- edi-entries: edi-8, edi-11, edi-17
1427
- note: review of all samplebuffer-related code;
1428
lots of code-cleanups and minor improvements
1429
- added: edi-11; hierarchy-based config file system;
1430
default values now stored to
1431
'{prefix}/share/ecasound/ecasoundrc' while
1432
individual values can be overridden in
1433
'~/.ecasound/ecasoundrc'
1434
- added: bitrate (kbps) params to mp3 and ogg outputs
1435
- added: initial JACK support; enable by giving
1436
--with-jack=install_prefix configure option
1437
- added: edi-8; ia-mode - support for parsing args
1438
containing white-space; either by quoting
1439
with ("a token") or backslash espacing
1440
(a\�token) [junichi]
1441
- removed: ecasoundrc - 'user-resource-directory' tag
1442
removed; user-specific preset/oscillator
1443
definition directory now '~/.ecasound'
1444
- changed: ecasoundrc - to avoid versioning conflicts,
1445
all 'ext-*' tags are renamed; see ecasoundrc(5)
1446
- changed: 'make install' will now overwrite old
1447
data files ({prefix}/share/ecasound/*)
1448
- fixed: problems with automake1.5
1449
- fixed: eiam - 'ao-get-position' returned an integer
1450
value instead of a float as it should
1451
- fixed: bugs with combining -ei and LADSPA plugins
1452
- fixed: 2.1dev5 wrote broken wav-headers
1453
- fixed: minor changes to posix signal handling
1454
- fixed: seg.faults with -ei:x where x < 50
1455
05122001 (v2.1dev5)
1456
- added: docs - Documentation/manpages.html
1457

1461
- changed: ecasoundrc - new defaults for mp3 and ogg
1462
output
1463
- changed: unified kvutils build process; added separate
1464
libkvutils_debug target; CXXFLAGS shared with
1465
ecasound build configuration
1466
- fixed: processing didn't stop with setups that had loop-
1467
devices connected to multiple input objects
1468
- fixed: using loop devices in setups with non-default
1469
internal sample rate could cause unwanted
1470
resampling
1471
- fixed: -kog and -f were broken (since dev4)
1472
- fixed: bugs in passing audio format params to
1473
mp3 and ogg encoders; note! update your
1474
~/.ecasoundrc to match the new defaults,
1475
see ecasoundrc(5) man page
1476
- fixed: ecasound wrote to ewf-files opened in read-only mode
1477
- fixed: work-around for environments without the C99 stdint.h
1478
header file [anarcat]
1479
- fixed: eiam - problems with 'cs-set-position-samples',
1480
'cs-rewind' and 'cs-forward' with unconnected
1481
chainsetups
1482
31102001 (v2.1dev4)
1483
- added: eiam - 'cs-option' commmand; although explicit use
1484
of cmd-line options as iactive-mod commands (like
1485
"-i:file.wav") is still supported, "cs-option
1486
-i:file.wav" is now the preferred syntax
1487
- removed: ecasound FAQ file - it only contains about
1488
a pageful of useful text - I moved that
1489
precious piece of content to the user's
1490
guide :)
1491
- changed: uses of '-i' an '-o' replaced with 'ai-add'
1492

1500
buffering mode was selected explicitly (-B)
1501
- fixed: eiam - minor 'cs-edit' bugs fixed

1507
can't execute ogg123 for ogg input
1508
21102001 (v2.1dev3)
1509

1514
- added: -z:multitrack, -z:nomultitrack for forced enabling
1515
and disabling of multitrack-mode
1516
- added: variable-like preset parameters; it's now possible
1517
to bind one preset parameter to multiple chainops'
1518
parameters (control multiple settings with one
1519
parameter)
1520
- added: support for describing preset parameters (edi-3)
1521
- changed: pyecasound - makefile-hack that allows pyecasound
1522
to work even though compiled against libecasound
1523
and libkvutils that are not installed to
1524
a directory listed in /etc/ld.so.conf
1525
- changed: db-subsystem - is put to sleep more
1526
aggressively, which should further decrease
1527
its cpu-load
1528
- changed: db-subsystem - runs once again under sched_fifo
1529
scheduling if -r is enabled
1530
- changed: ALSA xrun reports are now printed to stderr
1531
instead of ecasound debug-subsystem
1532
- changed: -B:rt selected as the default bmode for
1533
multitrack-setups (instead of -B:lowlatency)
1534
- changed: preset definitions in 'effect_presets' changed
1535
to take advantage of the preset system improvements
1536
- fixed: major bugs in interpreting LADSPA plugin
1537
parameter hint flags
1538
- fixed: a nasty bug in bufmode activation code prevented
1539
-kos, -kl, and others from working properly
1540
- fixed: loop devices didn't work well with -z:db; fixes

1543
by recent versions of ecamegapedal
1544

1545
if --disable-pyecasound was given to configure
1546
14102001 (v2.1dev2)
1547
- added: ecaplay - -k, -d and -h options, see 'man ecaplay'

- added: eiam - ai-get-length-samples, ao-get-length-samples,
1549
cs-get-length-samples, cs-set-length-samples [smassy]
1550
- added: support for variable length buffer's for ALSA 0.9
1551
output (required by -ei:xx type effects)
1552
- changed: tuned prefill-parameters for double-buffering
1553
- changed: when saving chainsetups, if no parameters
1554
are overridden, buffermode definition (-B) is
1555
saved instead of individual parameters
1556
- changed: yet more changes to the multitrack-mode
1557
- changed: eiam - output of *-status commands
1558
- fixed: -r option wasn't saved to chainsetups (used
1559
to be a session-level option)
1560
- fixed: typeselect problems when used for outputs
1561
- fixed: system lockups with -B:rtlowlatency and
1562
rt-object-only chainsetups
1563
- fixed: misplaced tab prevented eci.py from working
1564
with python 2.1 (nested scopes)
1565
- fixed: if a monitor track input ended before recording
1566
stopped in multitrack mode and -z:db was enabled,
1567
it continued producing unwanted noise to the
1568
monitor output
1569
- fixed: eiam - ladspa-register output had plugin names
1570
and descriptions mixed
1571
09102001 (v2.1dev1)
1572
- added: chainsetup parser prints a warning if an unknown
1573
buffering mode is given to -B:mode
1574

'rtlowlatency' if no chain operators are
1576
present, and multitrack mode is not active
1577
- changed: more improvements to double-buffering
1578
- fixed: critical bug when running in -B:rtlowlatency
1579
mode (caused system-lockups with ALSA 0.9.x
1580
oss-emulation)
1581
- fixed: explicitly specifying -z:nointbuf had no
1582
effect
1583
- fixed: setting double-buffer length didn't have
1584
any effect (given either in bmode defaults
1585
or as -z:db,dbsize)
1586
06102001 (v2.1dev0)

1591
affect old presets using -etd [smassy]
1592

1593
other name is given ('-o:alsa' is equivalent
1594
to '-o:alsa,default')
1595
- added: special case for mapping "ecasound file.ecs"
1596
to "ecasound -s:file.ecs"
1597

1598
is now completely transparent to other
1599
parts of ecasound
1600

1601
cs-get-position-samples, ai-set-position-samples,

1607
obsoletes old default-buffersize, etc options
1608
- added: various improvements to multitrack sync-mechanism
1609
to make it work reliably in all buffering modes

2155
was specified
2156

3.1.7 or newer required)
2344
- changed: cleaned up the audio object interface
2345
- changed: -f parameter format has changed - instead of

2390
defaults to 'false'
2391
- added: -z:psr option (see above)
2392
- changed: reimplemented signal handling using POSIX
2393
signal handlers (ANSI interface was used before)
2394
- changed: divided all the bigger modules into smaller
2395
classes and files (these big modules were
2396
causing lots of compiler and resource problems)
2397

2398
improved mixing algorithms, etc)
2399
- changed: rewritten mp3-support (still using mpg123 and lame)
2400

2404
- removed: 'sfx' command (iactive-mode)
2405

2414
- fixed: some finetuning of ALSA buffer handling

2417
with a 'd' in the version number
2418
- added: configure check for libdl library
2419
- added: "-eac:amp-%,channel" channel amplify
2420

- fixed: problems with libaudiofile (.aiff and .au/.snd
2430
support)
2431

2432
- fixed: qtecasound - chainsetup's name was changed to
2433
tempfile name if edited with an external editor
2434
- fixed: qtecasound - conflict with Qt-libs when
2435
stopping processing (resulted in abort)
2436
120999 (v1.5.11r5)
2437
- added: ldconfig is now always run after (un)install of
2438
binary RPM packages
2439
- added: if underruns/overruns occur when using ALSA devices,
2440
a warning message is given on exit (stderr)
2441
- changed: gcc's -fomit-frame-pointer isn't used anymore
2442
(caused lots of problems with exceptions)
2443
- fixed: ecasound tried to use ALSA headers even though
2444
--disable-alsa was given (eca-alsa-dyn.h and
2445
eca-midi.h)
2446
- fixed: audiofx_compressor.h tried to include obsolete
2447
error.h header file
2448
- fixed: pan effect (-epp) decreased overall volume level
2449
- fixed: fake-stereo effect (-etf) wasn't working properly

2454
- removed: simple lowpass filter (-ef2)
2455
070999 (v1.5.10r5)
2456
- added: qtecasound - file dialogs now remember the current
2457
directory
2458
- added: a much more elegant system for dynamically loading
2459
ALSA support
2460
- added: support for ALSA MIDI devices (/dev/snd/midiCxDy)
2461
- changed: rewrote the MIDI-input sybsystem (works better
2462
with multiple controllers)
2463
- fixed: kvutils -package also needed configure script fixes
2464
to recognise FreeBSD's pthread implementation
2465
- fixed: although "make install" worked in all cases,
2466
plain "make" didn't work if installing ecasound
2467
1.5.x for the first time
2468
- fixed: crashed if you had two chainsetups with ALSA devices
2469
and you tried to delete the other one
2470
- fixed: crashed in some conditions when closing .wav and
2471
.raw files
2472
040999 (v1.5.9r5)
2473
- changed: qtecasound - in all windows with list widgets,
2474
if no item is selected, current item (if any)
2475
is used for all operations
2476
- changed: in most cases, '-r' option (raise priority) isn't
2477
needed anymore (see ecasound and ecasoundrc man
2478
pages for more info)
2479
- changed ecasoundrc - 'x-text-editor-use-getenv' is now
2480
'true' by default
2481
- fixed: resonant lowpass filter was once again broken
2482
- fixed: configure should now recognise FreeBSD's pthread
2483
implementation (not tested yet)
2484
- fixed: in some rare cases, engine was started in interactive
2485
mixmode while the interface was in passive mode
2486
(-> program started but didn't do anything)
2487
030999 (v1.5.8r5)
2488
- added: '!' shortcut to all windows (keyboard focus to
2489
control panel)
2490
- changed: some Makefile changes for excluding static
2491
ecasound libraries from the binary dist packages
2492
(managed to shrink binary-rpms by nearly a 1MB!)
2493
- fixed: qtecasound - shortcut-key fixes in chainsetup window
2494
- fixed: qtecasound - waveform view positioning is now much
2495
more precise than before
2496
- fixed: qtecasound - core dumps when exiting
2497
020999 (v1.5.7r5)
2498
- added: qtecasound - chainsetup window now has a wave-edit
2499
button which loads the active file into a external
2500
wave editor; defaults to "snd", can be changed by
2501
changing the value of "x-wave-editor" in
2502
~/.ecasoundrc
2503
- added: qtecasound - support for external text editors
2504
(can be launched from session window) - saves the
2505
active chainsetup to a text file, loads it to an
2506
editor and afterwards updates file's content back
2507
to ecasound - if "x-text-editor-use-getenv true"
2508
is specified in ~/.ecasoundrc, ecasound uses
2509
EDITOR environment variable if it's available,
2510
otherwise value of "x-default-text-editor" is
2511
used ... an of course, default value for this is
2512
the ultimate musicians tool: emacs! ;)
2513
- changed: qtecasound - some minor changes to session and
2514
chainsetup widgets
2515
- changed: .ews format (wave view cache files) has changed,
2516
ecasound can still read the old format
2517
- changed: qtecasound - "activate" button changed to a
2518
"change status" button which rotates through
2519
inactive->active->connected->inactive ...
2520
- fixed: qtecasound - enabling/disabling chains sometimes
2521
resulted in program crashes
2522
- fixed: all structs found in ecasound source code now
2523
use the standard type definations from sys/type.h
2524
(format "[u_]int'bits'_t") - this should solve some
2525
compatibility problems with non-x86 platforms -
2526
thanks for Guenter Geiger for notifying about these
2527
- fixed: a few fixes to the new double-buffering system -
2528
lots of buffer parameter fine-tuning
2529
290899 (v1.5.6r5)
2530
- added: "-z:feature" command line option for enabling
2531
misc features
2532
- added: mmap-based double-buffering now disabled by
2533
default, enable it with "-z:db" or by putting
2534
"default-to-double-buffering true" to your
2535
~/.ecasoundrc
2536
- added: when upgrading ecasound, new resource values
2537
will be automatically added to your ~/.ecasoundrc
2538
- fixed: crashes when getting error messages from alsa-lib
2539
(for instance when using invalid card and device
2540
numbers)
2541
- fixed: a few Makefile problems in 1.5.x versions
2542
(thanks for Vadim Tkachenko for reporting these)
2543
280899 (v1.5.5r5)
2544
- added: improvements to resource file (~/.ecasoundrc)
2545
handling - resource files can now have comment
2546
lines (lines beginning with a '#'); resource
2547
files are rewritten only if resource values are
2548
changed directly from ecasound; '=' sign can be
2549
used as a name-value separator
2550
- fixed: since version 1.5.2r5, .cdr input/output hasn't
2551
worked (reversed byteorder when reading .crd
2552
files, .cdr output files weren't padded correctly)
2553
270899 (v1.5.4r5)
2554
- added: experimental support for double-buffered
2555
mmap() file i/o (currently implemented
2556
for .wav/.raw input only)
2557
- fixed: thread-priority was always risen (once again)
2558
210899 (v1.5.3r5)
2559
- added: a lowpass filter effect (-ef2); not as good
2560
as the other lowpass filters (-efl and -ef3), but
2561
should be a bit faster
2562
- fixed: 1.5.2r5 was really _slow_ (a file seek bug)
2563
200899 (v1.5.2r5)
2564
- added: "-x" command line option - truncate outputs
2565
- added: sample rate conversion (resampling) - if audio
2566
object's sample rate differs from ecasound's
2567
internal rate the signal gets resampled
2568
(internal rate is currently 44100; can be
2569
changed from samplebuffer.h)
2570
- changed: gcc 2.95.1 is now used when developing
2571
ecasound; precompiled packages require libstdc++
2572
2.10.0 (comes with gcc 2.95.1) or newer
2573
- fixed: few minor fixes to the noisegate effect
2574
- fixed: upon creation, more precision is used to print
2575
effect parameters
2576
190899 (v1.5.1r5)
2577
- fixed: problems with filters
2578
180899 (v1.5.0r5)
2579
- added: ecatools package which now consists of programs
2580
ecatools_normalize, ecatools_fixdc and
2581
ecatools_play - see ecatools(1) man page
2582
- changed: ecasound and qtecasound now have their own
2583
source trees; rest of ecasound is compiled
2584
into the libecasound.so shared library
2585
- changed: to make ecasound relocatable, preset files are now
2586
installed to standard data dir (defaults to
2587
/usr/local/share/ecasound)
2588
- changed: lot of source file name changes
2589
- changed: ALSA support (libasound.so library) is now loaded
2590
dynamically at runtime
2591
- fixed: you had to have yodl installed to to install ecasound
2592
man pages
2593
150899 (v1.4.6r5) -** public release **-
2594
- added: qtecasound - along with some other improvements,
2595
waveform widget now uses cache files to store
2596
wave statistics; for file "somefile.wav", cache
2597
file "somefile.wav.ews" is used
2598
- fixed: reading and writing aiff files works again;
2599
some aiff files created with sox still seem to
2600
cause trouble (might be a problem with
2601
libaudiofile)
2602
- fixed: qtecasound - a nasty mutex bug which caused ecasound
2603
to crash if you tried to use a chainsetup which has
2604
more inputs than chains
2605
120899 (v1.4.5r4):
2606
- added: qtecasound - dialogs for adding, removing and
2607
attaching inputs and outputs
2608
- added: support for null inputs/outputs
2609
- added: effect status is now printed when exiting ecasound
2610
(doesn't affect interactive mode)
2611
- added: if OSS drivers for your soundcard don't support
2612
trigger functions, you can disable these with
2613
configure option "--disable-osstrigger"
2614
- added: -ev effect (analyze sample data) now also tells
2615
how much the analyzed signal can be amplified
2616
without clipping
2617
- added: debug level can now be set in iactive mode with
2618
"debug level" command
2619
- changed: qtecasound - shortcuts a, A and ctrl-a now do
2620
the same thing; applies to all shortcuts
2621
- fixed: adding a chain without a valid output resulted in
2622
hangs when using multithreaded mixmode
2623
- fixed: didn't compile with alsa-lib versions older than 0.3.1
2624
- fixed: "ecasound -h" dumped core
2625
010899 (v1.4.4r4)
2626
- added: qtecasound - now asks for a name when adding chainsetups
2627
- added: qtecasound - adding and deleting chains
2628
- changed: some layout changes
2629
290799 (v1.4.3r4)
2630
- changed: if format supports it, outputs are now opened in
2631
read-write mode; currently supported by .wav,
2632
.cdr and .raw; when you use these as outputs, files
2633
aren't truncated if they exist
2634
- fixed: qtecasound - active chainsetup was always saved even
2635
if some other chainsetup was selected
2636
- fixed: qtecasound - crashed if you changed the active
2637
chainsetup and you had a waveform window open
2638
- fixed: qtecasound - crashed if tried to activate
2639
a invalid chainsetup
2640
- fixed: if you wrote to a output file, its length was
2641
not changed (from ecasound's viewpoint)
2642
270799 (v1.4.2r4)
2643
- fixed: samplebuffer.h still tried to include <soundcard.h>,
2644
which is both not necessary and a wrong place to
2645
look for it; thanks to Torbjorn Tornkvist and
2646
Xavier Hosxe for notifying me
2647
- fixed: qtecasound - using multithreaded mixmode, changing
2648
chainsetups on the fly caused a lot of problems
2649
- fixed: qtecasound - shortcut keys didn't work with CLI
2650
270799 (v1.4.1r4)
2651
- added: qtecasound - chain widget now monitors effect
2652
parameters
2653
- added: qtecasound - support for double clicks and return
2654
presses for various widgets
2655
- added: qtecasound - some new features to the waveform widget
2656
- changed: from now on, interactive mode isn't automatically
2657
enabled, if a realtime input is specified
2658
- changed: names of some functions (I'm trying to be careful
2659
how I use 'new' and 'add', 'load' and 'open', etc
2660
- fixed: qtecasound - waveform widget crashed qtecasound if
2661
the analyzed file had less than 76800 samples
2662
- fixed: if processing was completed and was restarted without
2663
a rewind/setpos, ecasound crashed/hang
2664
- fixed: raised-priority mode was sometimes enabled even
2665
without the -r option
2666
- fixed: qtecasound - when using multithreaded mixmode,
2667
exiting sometimes resulted in core dump or segfault
2668
250799 (v1.4.0r4)
2669
- added: qtecasound - waveform widget; graphical representation
2670
for input/output objects
2671
- added: qtecasound - chain widget; view chain status
2672
- added: qtecasound - chainsetup widget; status of input,
2673
output and chain objects, enable/disable chains
2674
- added: qtecasound - session-setup widget; load and save
2675
chainsetups, create new ones, etc
2676
- changed: can now be started without a valid chainsetup if
2677
interactive mode is enabled
2678
- fixed: *serious bug* if end of input was reached,
2679
that input remained silent until ecasound was
2680
restarted (has been broken since 1.3.0r3)
2681
240799 (v1.3.3r4)
2682
- added: -n option, sets chainsetup's name
2683
230799 (v1.3.2r4)
2684
- added: a new compressor - thanks for Viktor Endersz for
2685
sending it to me and John S. Dyson for coding it;
2686
it really works like a dream! (option -eca)
2687
- fixed: some fixes to my old compressor (now that we
2688
have a better one, this should be used only if
2689
you really want brutal results :))
2690
- fixed: due to some changes in ALSA libs, ecasound
2691
wouldn't compile with ALSA versions >0.3.2;
2692
haven't tested it, but should now work with both
2693
new and old ALSA libs
2694
200799 (v1.3.1r4) -** public release **-
2695
- fixed: delay effect was broken; while fixing this I also
2696
added a new surround mode, 2 = stereo-spread
2697
- fixed: more bugs with ALSA and OSS input routines;
2698
did some multitrack recording with both of them
2699
and got suprisingly good results (it seems that
2700
finding the optimal buffer size is the key to success)
2701
190799 (v1.3.0r3)
2702
- added: support for sessions and chainsetups; now you can
2703
store the whole runtime setup to an ascii file and
2704
load it back; the syntax used is exactly the
2705
same as the command line syntax so editing these
2706
saved chainsetup files is easy
2707
- added: "-s[:]filename" command line option for loading
2708
chainsetup files
2709
- added: "load filename" and "save filename" commands to
2710
the interactive-mode (for chainsetups)
2711
- added: support for libaudiofile (SGI audiofile) library;
2712
new file formats: .aiff, .au and .snd; (linking to
2713
audiofile can be prevented with --disable-audiofile
2714
option to the configure script)
2715
- added: -q option (quiet mode), disables all output
2716
- added: support for raw/headerless (.raw) input/output files
2717
- added: support for using standard system input and output
2718
streams (-i:stdin, -o:stdout)
2719
- added: finished the man pages, all important options and
2720
features should now be covered
2721
- fixed: file name ending with a upper-case extension
2722
wasn't recognised
2723
- fixed: when using multithreaded mixmode with complex setups,
2724
threads sometimes went out of sync causing strange
2725
behaviour
2726
- changed: size of sample buffer objects can now be changed
2727
on-the-fly (output files are not aligned to
2728
buffersize anymore) -> this makes ecasound more
2729
usable as a format conversion tool
2730
- changed: compressor wasn't working, decided to code
2731
a new one (still experimental but works better
2732
than the last one)
2733
140799 (v1.2.3r3)
2734
- added: support for .mp2 files
2735
- fixed: still some bugs in selecting mixmode
2736
- fixed: automatic stereo-mono conversion wasn't working
2737
at all (as all chains are internally stereo, this
2738
occured everytime you specified a mono output, even
2739
if the input was mono, too)
2740
130799 (v1.2.2r3)
2741
- added: ALSA devices can now also be opened by specifying
2742
the actual device name (/dev/snd/pcm...)
2743
- changed: default output is now always attached to chain 'all'
2744
- fixed: start/stop/forward/rewind with ALSA-output sometimes
2745
resulted in loud crackle
2746
- fixed: some bugs in the position slider of qtecasound
2747
- fixed: 'noise-gate-mono' effect was rewritten as it didn't
2748
seem to work very well
2749
120799 (v1.2.1r3) -** public release **-
2750
- added: 'make install' now creates /etc/ecasound directory
2751
and copies all the configuration/preset files
2752
to this directory (existing files/dirs are skipped)
2753
- added: lots of crash-guards to command line parsing
2754
- added: frequently-asked-questions file (both txt and html)
2755
- added: new options to the configure script: --disable-alsa,
2756
--disable-oss and --disable-qt
2757
- fixed: bugs in mixmode multithreaded-iactive (crashed
2758
pretty much everytime)
2759
- fixed: estatus output was sometimes pretty messy
2760
110799 (v1.2.0r2)
2761
- added: support for ALSA input/output
2762
- added: a lot of new documentation to the man pages
2763
- added: new configurable options to ~/.ecasoundrc
2764
(default-buffersize, default-to-interactive-mode,
2765
default-to-raisepriority)
2766
- added: finally implemented the 'help' command in
2767
the interactive-mode; also added a prompt, which
2768
should help a bit :)
2769
- added: autoconf and automake additions; now qtecasound is
2770
compiled only if qt library is found, OSS and
2771
ALSA modules are compiled if the necessary
2772
headers and libraries are available
2773
- added: support for single-chain effect presets (-ps command
2774
line option)
2775
- fixed: bugs with OSS-input (device was sometimes closed
2776
