-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hey Gang, I figured this is a frequently asked question, however it is not in the faq. i am wondering the lowest possible bit-rate to stream ogg at. is this an ogg limitation or is this dependent on the streaming server.

Tho it sounded like crap. It'll soon be possible to stream Ogg Speex through Icecast, which will be capable of lower with voice content. --- >8 ---- List archives: http://www.xiph.org/archives/ icecast project homepage: http://www.icecast.org/ To unsubscribe from this list, send a message to 'icecast-request@xiph.org' containing only the word 'unsubscribe' in the body.

I also encode at 11khz and get about 8 kbps. It sounds roughly comparable to our 16K RealAudio stream: crap, but at half the bitrate. Search around for a thread on the "Vorbis GT3" encoder. Someone did some impressive work tweaking ogg vorbis to emit reasonably listenable sounds at 4-5Kbps, stereo even. A back burner project of mine is to merge his code with current vorbis sources so we can stream something intelligible at the lowest possible bitrate. Speex would be cool, too, but getting our listeners to install vorbis plugins, etc., is enough of a challenge for now.
