The distortion effect simulates a MOSFET preamplifier with adjustable
15
clipping. With a mode parameter one can switch between a halfwave and a
16
fullwave rectifying output stage.

`distortion' parameters

.......................
32
This parameters set the amount of signal gain before the signals
33
enters the distortion stage. The more pregain you set the more
34
dramatic the distortion becomes. Good values are between 10.0 and
35
20.0, defaults to 10.0
38
The distorted signal and the dry signal are mixed at the output.
39
fxgain sets the amount of effect signal added to the dry signal,
43
asym sets the signal midlevel for clipping. In mode 0 the signal
44
is clipped if it's smaller than asym-clip or greater than
45
asym+clip, e.g. clip=0.5 and asym=0.5 simulates a halfwave
46
rectifier. Setting these values allows you to modify the harmonic
47
content of the distorted signal. In mode 1 the signal is fully
48
rectified and clipped at level <clip>.
52
`0 enables asymmetrical clipping mode'
54
`1 enables fullwave rectifying mode'

Glame provides a simple framework of FFT filters to allow for the
62
application of effects in the frequency domain of sample sounds. The
63
core plugins are fft and ifft using the specially designed FFT protocol
64
which supports adjustable FFT blocksizes and oversampling. All FFT
65
processing is done based on the fftw (<http://www.fftw.org>) library.

Input stream of sample data. Only one connection is allowed.

Output stream of fft data. Only one connection is allowed.
94
This parameter sets the blocksize for the FFT. The higher the
95
value the better the frequency resolution of the transformation.
98
To enhance the time resolution of the signal and thereby the
99
quality of the resynthesized sound it is necessary to do
100
oversampling. A good factor is the default value of 8.

The ifft plugin doesn't need any parameters. blocksize and oversampling

183
Implements a five band equalizer in the frequency domain. It features a
184
low, midlow, mid, midhigh and high band which are equally distributed
185
over the frequency range. This distribution is not really usable, but
186
it's a proove of concept at the present time..

233
The normalize function can be invoked from the main menu or from the
234
waveeditor widget. Normalize scans all given tracks for the highest
235
peak in amplitude or the highest RMS peak for a given frequency window.
236
You can normalize the signal in three different modes:
238
The maximum peak is adjusted to 1.0 with a factor given by the 1.0
239
divided by the max. peak.
242
The maximum peak is adjusted to the given amplitude(either
246
The signal is scanned for the highest RMS energy in the given
247
frequency and then adjusted to the given amplitude (either
248
absolute or dB). By pressing the analyze button in the normalize
249
GUI, the file is just scanned and the found results are presented in
250
the text box. If you don't press analyze, this step is done
251
automatically after pressing the ok button.

The fade in (and out) operations fade in (or out) the current selection
260
linearly. These operations are only useful if invoked through the
261
context menu of the waveedit window.
