What are the desired specs? i.e. How low does the input frequency need to be able to go? And how flat does the DC output need to be? You might have trouble at low frequencies. I once designed one of these that had to be fast and work from 30 Hz to 22 kHz, and had to resort to some trickery to adjust some of the circuit parameters versus frequency.

By the way, have you tried LT-Spice? You can use WAV files as inputs (and outputs), with LT-Spice. It's free, at linear.com . And there's a truly-excellent support group for it, at yahoogroups.com.
