And why are you limiting this to V.32 (9600bps)? V.32bis (14.4k bps) modem chips cost maybe 20% more than v.32 chips in quantity.
at Interopt I heard some voice demos that were at 9600 4800 and 2400 baud the 2400 sounded a phoneme chip but was *very* resionable.
Quite likely what you heard were 9600/4800/2400bps (bits per second), not baud. The two are different. 2400bps compression of voice is quite a bit beyond current GP CPUs. Also, note that 9600 baud (V.32 carriers) are based on a 2400bps carrier. (And if they're not, I'm sure someone will correct me.) 2400 baud modems are based a bit rate something less than 2400bps, though I can't remember exactly what it is right now. Jim
