If this is not the proper list for this type of question, please direct me to the correct one and I'll post similar queries there in the future. I've been happily using rc3 since shortly after its release and slowly converting the music collection on my PC from mp3 to ogg. I've now run into a problem that has me stumped. On the 2nd track of The Breeders _Last Splash_ album, the intro bass riff comes up with some frickin' /nasty/ artifacts that vorbis has never given me before; like it's been dropping samples. The test cases I've run so far are -q 4, -q 5, -q 9, and -b 128. The CD itself plays fine, as does the .wav from which I'm encoding. LAME doesn't seem to mind, either. I'm (still) running Red Hat 6.2, and I remember someone mentioning some problems with an older version of glib or glibc, but I upgraded as far as I could without breaking 4,067 or so dependencies. I now have: glib-1.2.8-1 glibc-2.1.3-23 egcs-1.1.2-30 Any ideas?

If you're reencoding from mp3 to Ogg, don't expect any quality at neither quality level. Reencoding is a Bad Thing To Do, only encode from the source, i.e. CDs. If you're already doing that, a losslessly (FLAC) encoded demo clip of the problematic part plus a .ogg, at a reasonable quality setting, with the artifact (and a description of it if it's hard to hear), could help the developers to improve the encoder or fix it, if it's a bug. <p>Moritz --- >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.

The version that ships with RH6.2 has a known bug with -O2 that affects Vorbis. -- 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...
