I want to know speex compression rate. On the speex website,it says" Speex is based on CELP and is designed to compress voice at bitrates ranging from 2 to 44 kbps." Is the original voice at bitrates raning from 2 to 44 kbps,or the compressed voice at bits ranging from 2 to 44 kbps? what is the maxmium compression rate? Thanks a lot!

The input bit-rate doesn't mean much because it depends on how you were representing it (u-law, 16-bit, float, ASCII, ...). Jean-Marc
You can pretty much tune the compression (bitrate of the encoded audio) to anything within the range stated on the website. The input audio bitrate is irrelevant. //JT -----Ursprungligt meddelande----- Fr?n: speex-dev-bounces@xiph.org [mailto:speex-dev-bounces@xiph.org] F?r ??
