Build a one or two bit ADC and feed it into a home built DAC of the same 
bit depth.  A few resistors, comparators, simple logic gates, batteries, 
micsellaneous stuff is all it should take.

What would happen if you set a VCO to 20kHz (or more), and pulse width 
modulated it with your audio signal?
