http://audio.ciara.us/test/index.html http://audio.ciara.us/test/128extension/results.html AAC, MPC, Vorbis, WMA 9/Pro, Lame & Blade were tested at 128k vbr. MP3Pro, AAC-Pro/Plus(?) and older versions of WMA were not tested. Looks like Vorbis tied with AAC, MPC and WMA 9/Pro for first. Although it was a four way tie, Vorbis was on the low end. And LAME was only slightly lower, comming in at second. And didn't I hear in here that MPC is actually going open source? (Hmm.... I guess that would mean two of the best codecs will end up being open source.) Looks like it's time to start improving vorbis.... <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.

It would be interesting to redo the test with Garf's tuned version.> Looks like it's time to start improving vorbis....Does anyone know if Garf's tuning have been folded into the main branch?

You have to realise that the Oggs in these tests were encoded at -q4.25, which is below the range Garf's latest stuff is tuned for. So this really looks like the current state of the art as far as Vorbis is concerned. <p>>> no, Garf's tunings have not made it into the CVS as yet.>Too bad. Do you know if and when that will happen?<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.
