.TH "METAFLAC" "1" "02 January 2003" "" ""
8
metaflac \- program to list, add, remove, or edit metadata in one or more FLAC files.
11
\fBmetaflac\fR [ \fB\fIoptions\fB\fR ] [ \fB\fIoperations\fB\fR ] \fB\fIFLACfile\fB\fR\fI ...\fR
15
Use \fBmetaflac\fR to list, add, remove, or edit
16
metadata in one or more FLAC files. You may perform one major operation,
17
or many shorthand operations at a time.
20
\fB--preserve-modtime\fR
21
Preserve the original modification time in spite of edits.
24
Prefix each output line with the FLAC file name (the default if
25
more than one FLAC file is specified).
28
Do not prefix each output line with the FLAC file name (the default
29
if only one FLAC file is specified).
31
\fB--dont-use-padding\fR
32
By default metaflac tries to use padding where possible to avoid
33
rewriting the entire file if the metadata size changes. Use this
34
option to tell metaflac to not take advantage of padding this way.
35
.SH "SHORTHAND OPERATIONS"
38
Show the MD5 signature from the STREAMINFO block.
40
\fB--show-min-blocksize\fR
41
Show the minimum block size from the STREAMINFO block.
43
\fB--show-max-blocksize\fR
44
Show the maximum block size from the STREAMINFO block.
46
\fB--show-min-framesize\fR
47
Show the minimum frame size from the STREAMINFO block.
49
\fB--show-max-framesize\fR
50
Show the maximum frame size from the STREAMINFO block.
52
\fB--show-sample-rate\fR
53
Show the sample rate from the STREAMINFO block.
56
Show the number of channels from the STREAMINFO block.
59
Show the # of bits per sample from the STREAMINFO block.
61
\fB--show-total-samples\fR
62
Show the total # of samples from the STREAMINFO block.
64
\fB--show-vc-vendor\fR
65
Show the vendor string from the VORBIS_COMMENT block.
67
\fB--show-vc-field=name\fR
68
Show all Vorbis comment fields where the the field name matches
71
\fB--remove-vc-field=name\fR
72
Remove all Vorbis comment fields whose field name is 'name'.
74
\fB--remove-vc-firstfield=name\fR
75
Remove first Vorbis comment field whose field name is 'name'.
78
Remove all Vorbis comment fields, leaving only the vendor string
79
in the VORBIS_COMMENT block.
81
\fB--set-vc-field=field\fR
82
Add a Vorbis comment field. The field must comply with the
83
Vorbis comment spec, of the form "NAME=VALUE". If there is
84
currently no VORBIS_COMMENT block, one will be created.
86
\fB--import-vc-from=file\fR
87
Import Vorbis comments from a file. Use '-' for stdin. Each
88
line should be of the form NAME=VALUE. Multi-line comments
89
are currently not supported. Specify --remove-vc-all and/or
90
--no-utf8-convert before --import-vc-from if necessary.
92
\fB--export-vc-to=file\fR
93
Export Vorbis comments to a file. Use '-' for stdin. Each
94
line will be of the form NAME=VALUE. Specify
95
--no-utf8-convert if necessary.
97
\fB--import-cuesheet-from=file\fR
98
Import a cuesheet from a file. Only one FLAC file may be
99
specified. A seekpoint will be added for each index point in
100
the cuesheet to the SEEKTABLE unless --no-cued-seekpoints is
103
\fB--export-cuesheet-to=file\fR
104
Export CUESHEET block to a cuesheet file, suitable for use by
105
CD authoring software. Use '-' for stdin. Only one FLAC file
106
may be specified on the command line.
108
\fB--add-replay-gain\fR
109
Calculates the title and album gains/peaks of the given FLAC
110
files as if all the files were part of one album, then stores
111
them in the VORBIS_COMMENT block. The tags are the same as
112
those used by vorbisgain. Existing ReplayGain tags will be
113
replaced. If only one FLAC file is given, the album and title
114
gains will be the same. Since this operation requires two
115
passes, it is always executed last, after all other operations
116
have been completed and written to disk. All FLAC files
117
specified must have the same resolution, sample rate, and
118
number of channels. The sample rate must be one of 8, 11.025,
119
12, 16, 22.05, 24, 32, 44.1, or 48 kHz.
121
\fB--add-seekpoint={\fI#\fB|\fIX\fB|\fI#x\fB|\fI#s\fB}\fR
122
Add seek points to a SEEKTABLE block. Using #, a seek point at
123
that sample number is added. Using X, a placeholder point is
124
added at the end of a the table. Using #x, # evenly spaced seek
125
points will be added, the first being at sample 0. Using #s, a
126
seekpoint will be added every # seconds (# does not have to be a
127
whole number; it can be, for example, 9.5, meaning a seekpoint
128
every 9.5 seconds). If no SEEKTABLE block exists, one will be
129
created. If one already exists, points will be added to the
130
existing table, and any duplicates will be turned into placeholder
131
points. You may use many --add-seekpoint options; the resulting
132
SEEKTABLE will be the unique-ified union of all such values.
133
Example: --add-seekpoint=100x --add-seekpoint=3.5s will add 100
134
evenly spaced seekpoints and a seekpoint every 3.5 seconds.
136
\fB--add-padding=length\fR
137
Add a padding block of the given length (in bytes). The overall
138
length of the new block will be 4 + length; the extra 4 bytes is
139
for the metadata block header.
140
.SH "MAJOR OPERATIONS"
143
List the contents of one or more metadata blocks to stdout. By
144
default, all metadata blocks are listed in text format. Use the
145
following options to change this behavior:
148
\fB--block-number=#[,#[...]]\fR
149
An optional comma-separated list of block numbers to display.
150
The first block, the STREAMINFO block, is block 0.
152
\fB--block-type=type[,type[...]]\fR
154
\fB--except-block-type=type[,type[...]]\fR
155
An optional comma-separated list of block types to included
156
or ignored with this option. Use only one of --block-type or
157
--except-block-type. The valid block types are: STREAMINFO,
158
PADDING, APPLICATION, SEEKTABLE, VORBIS_COMMENT. You may
159
narrow down the types of APPLICATION blocks displayed as
162
APPLICATION:abcd The APPLICATION block(s) whose textual repre-
163
sentation of the 4-byte ID is "abcd"
164
APPLICATION:0xXXXXXXXX The APPLICATION block(s) whose hexadecimal big-
165
endian representation of the 4-byte ID is
166
"0xXXXXXXXX". For the example "abcd" above the
167
hexadecimal equivalalent is 0x61626364
171
if both --block-number and --[except-]block-type are
172
specified, the result is the logical AND of both
176
\fB--application-data-format=hexdump|text\fR
177
If the application block you are displaying contains binary
178
data but your --data-format=text, you can display a hex dump
179
of the application data contents instead using
180
--application-data-format=hexdump.
184
Remove one or more metadata blocks from the metadata. Unless
185
--dont-use-padding is specified, the blocks will be replaced with
186
padding. You may not remove the STREAMINFO block.
189
\fB--block-number=#[,#[...]]\fR
191
\fB--block-type=type[,type[...]]\fR
193
\fB--except-block-type=type[,type[...]]\fR
194
See --list above for usage.
198
if both --block-number and --[except-]block-type are
199
specified, the result is the logical AND of both arguments.
204
Remove all metadata blocks (except the STREAMINFO block) from the
205
metadata. Unless --dont-use-padding is specified, the blocks will
206
be replaced with padding.
208
\fB--merge-padding\fR
209
Merge adjacent PADDING blocks into single blocks.
212
Move all PADDING blocks to the end of the metadata and merge them
