THAT matters. 128kb/s is pushing it for Mpeg-2 Layer 3. It's NOT pushing it for MPEG-2 AAC, and even 192 kb/s is pushing it for MPEG-1/2 Layer 2. It all depends on bit rate and coder. At 256 kb/s/stereo pair, MP3 is REAL good. -- Copyright jj@research.att.com 1998, all rights reserved, except transmission by USENET and like facilities granted. This notice must be included.
