   What you're looking for is generally called a "balanced" modulator (or
   mixer); it is, among other things, used extensively in generating
   single-sideband radio transmissions.  As a good starting place, I'd
   recommend the American Radio Relay League (ARRL) "Radio Amateur's Handbook".


that is certainly the convential approach, but something like the new
motorola single chipper which has just enough dsp umph to work on
audio would work very nicely, too (as long as you are trying to
modulate two audio signals, not one audio and one rf).

REALLY, instead of hyping low impact soles, I think what we need
are more low impact souls.
