Greatly concerned for size, i just ripped an audio cd @ 22050kHz and mono sound. Encoding using 'oggenc -b 1 -', the resulting Ogg file is around 30kb/s. During the encoding process i was "warned" that the encoder is tuned toward 44.1kHz and encoding files in any other may result in degraded quality. How worried should I be? Is the advantage in size lost due to crappy quality (versus 44.1kHz mono files)? comment: twinhq 96kb/s and oggvorbis beta4 ~100kb/s are virtually identical. however, once twinhq is dropped down to 80kb/s, all hell breaks loss and they sound shot-to-shit. they hardly compare to 50kb/s OggVorbis files. I used the latest version of the twinhq encoder (as of last week). -- noodlez: Karol Pietrzak GPG/PGP-KeyID: 0x3A1446A0 --- >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.

If not, then I guess you should be worried :) Obviously, you're saving a lot in bitrate by doing this, but you have a corresponding loss in quality - the question is whether (for you/your purposes) that loss is acceptable.

Hi: The warning is there because the vorbis encoder hasn't been tuned to deal with things like preecho etc at lower sampling rates. I have noticed a bit of this at 11khz. Frankly, I think that 22khz mono sounds great at the lowest encoder mode. Since you seem prepared to live with 22khz mono then you should find this mode more than satisfying (IMHO).
