Regarding the 128 bps, it really depends on the encoder. Fraunhoffer (sp)
encoders tend to be the best, and if you use the codec in a good program,
anything above 128 will essentially sound like 128.
Of course, finding good codecs is often a problem, and a lot are
commercial, so yes, using a higher bitrate is a good solution. Less
compression = less problems.
One interesting aspect of encoding is the VBR, or variable bit-rate,
encoding capabilities of the latest version of AcidPro. In the export
function, it can export to mp3 and use variable bitrate, meaning that it
detects when there is more sound (uses less compression) or more silence
(uses more compression). It actually seems to be highly efficient too,
meaning that there aren't many mistakes, and you have well-compressed areas
where there isn't much music, and the 'important' parts with music aren't
compressed as bad. The result - efficient and often smaller mp3's of a
surprisingly good quality. You end up having an mp3 that changes bitrates a
lot, sure, but it just make's winamp/etc.'s screen upset - it doesn't
affect playback. It's too bad there aren't more encoders like this.
However, I'm not sure how something like that would work on decompressing...
