Arg, I think I am wrong,
I heard about Realserver for Linux, but I am not sure if it includes an
encoder. Anyway I try to avoid proprietary codecs.
( Realnetworks still not able to deliver a decent realplayer for linux,
my guess is that if they do not open their protocols , Microsoft will kill
them just like they did with Nescape
.. hopefully there will be a Mozilla-of-the-streaming-protocols :-) )


But as Artur pointed out, GSM isn't that bad at 12kbit/sec,
plu when searching around the net I found a voice coder which runs
at about 4.8kbit/sec .

or if you want extreme low bit rates use the LPC-10 code , down to 2.4kbit/sec,
= 1.1MB/hour  :-)

But I don't know if the quality high enough for you
