Okay, I'm not sure if I was using the proper phrase now. There are two
devices that do similar things. I think I was referring to one device,
while you were thinking of the other.

The device I am thinking of is similar to technology used in SSB radio
communications. It involves balanced modulators, demodulators, precise
filtering, and generation of a carrier signal well above audio frequencies.
Basically, it's a self-contained SSB transmitter and receiver all in one
module.

Was "pitch shifter" the wrong term? If so, what's the correct term? It
might even be called something different in your country than here in the USA.
