A codec "comparison" a la Microsoft:

this one will download and auto-install into your Media Player 7 or 8. It features one SQAM sample. You can listen to the original sample and to the difference between WMA/MP3/RA and the original. They claim: the less difference, the better the encoding.

They also quote a "report" on audio quality which you will find on the following URLs. Since they financed that report, of course WMA wins wink.gif Well, if they had added AAC to the comparison, they had probably lost big time...

Have fun. I'd like to hear your opinions about that Microsoft marketing wink.gif

they probably used the worst MP3 decoder they could find wink.gif

I was impressed, however, how well WMA handled the sharp attack on the SQAM test sample. It's a very typical example where an MP3 codec would switch to short blocks in order to avoid pre echo.

Not too far from the truth - according to the page they used WinAmp 2.10, and looking at the Winamp changelog I see this in the next version (2.20):

All new better sounding, industry standard Fraunhoffer MP3 decoder

Sorry, meant to say encoder. The decoder doesn't have much influence on the audio, if it's properly implemented.
