[sdiy] Vocoder

[JH.]

I found a source of 1% polypropylen capacitors.
You need about 150 pieces of 10nF, and 150 pieces of 47nF.
If you buy in these quantities, they are quite affordable.

Hi Juergen,

Nice looking simulation, but how does it look with component variation 
within their tolerances? Or do you plan to select capacitors and (if 
any) inductors?

Best regards,
Simon
