[MP3 ENCODER] Decoder comparisons at shoutclub.net

2000-06-21 Thread Mathew Hendry
Following on from the recent decoder quality discussions, some may find this interesting. http://players.shoutclub.net/wavcompare/ Winamp does uniformly badly, but Sonique 1.5's results are a little strange - very close to the reference (l3dec) in some tests, miles away in others. -- Mat. --

I saw a disturbing report tonight on the Register http://www.theregister.co.uk/content/1/11499.html which indicates hardware manufacturers may be set to dump MP3 in favour of AAC. Hard to estimate what kind of a threat S3's adoption of AAC will pose for MP3 - but the quality/filesize ratio is b
