Congratulations on inclusion in the Real Helix thing. :-) I do have a question, however. While I am very impressed by Vorbis 1.0's quality even down to "-1", vorbis seems very much a VBR format, which is great if the file lives on your hard drive, but a mixed bag for streaming over a modem connection. How well does Vorbis compare to existing streaming formats, including Real's native ones? -Steve <p><p><p><p>--- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'vorbis-request@xiph.org' containing only the word 'unsubscribe' in the body.

Go to <http://ff123.net/64test/testplan.html> and participate in the 64kbps listening test. (A Windows machine with a sound card is required.) Then you'll not only know how good (or bad) Vorbis is compared to and WMA, AAC, and MP3Pro -- you'll have a chance to send valuable feedback to the Vorbis team and others to help improve the quality. -- Greg Wooledge | "Truth belongs to everybody." greg@wooledge.org | - The Red Hot Chili Peppers http://wooledge.org/~greg/ | -------------- next part -------------- A non-text attachment was scrubbed...

They just fake it so they appear to be CBR sometimes :-) Vorbis can do this too - the encoder can (though it won't by default) use constrained bitrates (you can make it CBR - but more usefully for streaming, you can also do things like setting a maximum bitrate for the encoder to use).
