I remember reading somewhere that a feature of Vorbis is that you can scale down the bitrate without re-encoding, but I can't find it now. Its intended for internet streaming, I'm guessing Icecast can do it but its ment for streaming, not working on files... 320kbps Vorbis seems a bit... excessive to me. The FAQ lists quality 5/160kbps as being near CD quality, and thats the setting I use... I've done extensive testing with LAME/MP3 at various bitrates, and found ~160kbps VBR to have no noticeable artifacts, even if I threw the worst stuff I could find at it. Now considering that I've had to pull Vorbis down below 100kbps to start hearing ANY artifacts, 160kbps ogg/vorbis is more than enough for me... Interestingly, Vorbis's approach to compression seems to actually do BETTER with noisy, busy sound (The Chemical Brothers: Dig Your Own Hole...) that make MP3 break down and cry. The VBR bitrates for Chemical Brothers tend to average lower than those for, say, Weird Al, whereas its the opposite for LAME/MP3... OGG/Vorbis kicks ass. -------------- next part -------------- A non-text attachment was scrubbed...
