Linux RA-player has been around for quite some time now, but I've > never heard about a RA-encoder for Linux! :o > 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 http://www.arl.wustl.edu/~jaf/lpc/ Benno.
