Yeah, yeah, I know the license says don't do it. Be sneaky. Of course, I think it just boils down to 'Microsoft has an odd definition of CD quality". But I won't know that till hearing the samples.

I'd imagine they're stereo, but if they're not, well, geez :-) Monty --- >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.

What kind of codec is the WMA? MDCT, wavelet, vertor quant, whatever?

My only problem is finding a copy of media player 6.4 for windows 95. It's not meant to be compatible with older versions, though it does seem to play on mine. I'd rather get 6.4 though because that's what they say it's compatible with.> Of course, I think it just boils down to 'Microsoft has an odd > definition of CD quality". But I won't know that till hearing the samples.I did get realplayer 8 for linux and the samples MS have to compare with realplayer 8 are, upon first listen, pretty impressive. However, if you listen for longer, you do notice a rather weird bubbly sort of artifact for sounds up to about 500 hz or so. I really notice them at the extreme left and extreme right of stereo samples. It's as if the joint stereo is *very* joint. I heard a stereo stream at 20 point something kbps which sounded like 22khz. This stream was a stereo recording of a classical piano piece. The result was a rather toppy centre that sounded like it was across the room a little, and sides that were rolled off at, as I say, around 500 hz. There was some swurling, phasing oddities and some pre-echo problems. anyway, I can put up wavs of the MS realaudio 8 samples too if you want.> (also, are those mono or stereo samples?
