_I_ thought you were talking "uncompressed" 11025 8-bit samples/sec -
which is low quality, but common enough.

MP3 will indeed do 16kbps, and with Fraunhofer's low bitrate extensions,
8kbps. Adequate for voice and fits fine over a modem.

If we're mainly aiming at voice, in fact, we can do even better - fire
up Speak Freely for UNIX and there's a raft of choices, including 13kbps
for decent quality GSM and 2400bps (!) for LPC-10.
