the "filter input" is treated as in the compressor patch \, multiplying
each channel amplitude by one over its modulus (but limited by the
"squelch" parameter.) It is then multiplied by the modulus of the channel
amplitude for the control source (which is Fourier analyzed in parallel
with the filter input.);

#X text 27 35 This is a Fourier-based "vocoder" (perhaps better called
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.;
