[sdiy] Lin/Log VCAs and envelopes - compensating for log VCAs

Hi Richie,

Around about 00:37 he says the exponential attack portion is due to
the charging of a capacitor from a constant current source.

Ewwww....!!!!

If it was a constant current source it would not be exponential.  It
would be a straight line.  You get exponential when charhing through a
resistor.
