for instance, (for further use as a modulation signal or for your pure
listening pleasure) and the VCA is modulated quickly. If the signal has a
DC offset, this offset voltage will of course also be modulated by the VCA,
and out comes the VCA modulation signal... which you probably don't want
there, especially if the VCA is modulated in or near the audio spectrum.
