Vocoder design

[Scott Bernardi]

If it does require more than 12db/octave filters, I think the circuit gets too complex. Also, the phase changes would get
pretty crazy, I think.
One thing I was going to try is alternate the polarity of the inputs on each channel so the responses between the channels
would add, and therefore flatten out the overall response.
