- 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.
