a "timbre stamp") like the one the Convolution brothers use. The "control
|
|
source" is analyzed to get its spectral envelope \, which is then stamped
|
|
onto the "filter input" by adjusting the amplitudes of its Fourier
|
|
transform. The "filter input" is first whitened by the compression
|
|
algorithm from the previous patch in this series. The best value of
|
|
"squelch" to use depends critically on what kind of sounds are used
|
|
for the filter input and the control source.;
