Hi all! I ran across another song that oggenc seems to have trouble to encode. The intro of U2:s "Grace" gets its right channel messed up by oggenc, even at the highest bitrate. Why is the bitrate only 218? Isn't that awfully little when asking for 320? Qualityflaws like these is the reason i prefer mp3 and mpplus today. But vorbis is getting better for every beta, so keep up the good work! =) If you want to listen to the files: http://www.dtek.chalmers.se/~d99papa/files/ /Erik>oggenc -b320 grace.wavOpening with wav module: WAV file reader Encoding "grace.ogg" [ 10.8%] [ 1m31s remaining] \ Done encoding file "grace.ogg" File length: 0m 35.0s Elapsed time: 0m 11.0s Rate: 3.2423 Average bitrate: 217.9 kb/s>oggenc -hOggEnc v0.7 (libvorbis beta4) --- >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.

You should upload a part of the .wav file which sounds bad, so that everyone can test it (especially the developers).

Are you sure you're using the latest encoder/decode? I remember posting a similar message to yours and when I upgraded all the problems vanished, red faces all round. nb. You have to get both the encoder *and* the decoder right. As for the bitrate, maybe 218 is enough to encode the track perfectly with no loss. That track doesn't exactly have a lot of high frequencies or harmonics in it. Ogg is just saving you some disk space.... :-) -- <\___/> / O O \ \_____/ FTB. --- >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.

I have verified what Erik hears using the beta 4 oggdrop encoder and Peter's Winamp plugin decoder (v 1.01). In spectral view, it shows up as very long duration (up to 1 second) dropouts between 3 and 9 kHz. ff123 --- >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.

Hello folks, I was wondering what people's thoughts are on the best quality settings are for encoding ogg (linux). I'm thinking this as i hear about bitrate peeling and the like which may help me in the future should i want lower bitrates. At the moment for building a jukebox and band recorder i'm after the best sounding settings rather than space, and without moving towards FLAC... (ok, so space is a little issue or i wouldn't be asking this question). The signal is into some real nice output gear so is why i need a good sound source. What are the benefits for using extreamly high bitrates? Any comments would be primo!

i think negative quality wouldn't make sense. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ AndyCool22 on AOL Instant Messenger AndyCool22@PeoplePC.com http://www.livejournal.com/users/andycool22/ ¸_./'\._¸ ¸.·¤**¤·.¸.·¤**¤·.. *·. .·* *Andy Dale* /.·*·.\*.·¤**¤·.¸¸.·¤**¤·.* ICQ # 76178574 andycool22@msn.com on MSN Messenger andycool22@yahoo.com on Yahoo!
