I would really really suggest that the iPaq community have a look at
madplay (http://www.mars.org/home/rob/proj/mpeg/).

I personally hacked one of the first fixed point MP3 players (namely
splay) more than one year ago. Even if it was more performant than most
alternatives, the accuracy i.e. sound quality of splay doesn't even
qualify for the minimum ISO/IEC compliance. The madplay site features a
comparison of many MP3 players, notably all known available fixed point
based ones. Among all of them, mpg123 is __the worst__ one. Even worse
than splay. On the other hand, madplay is the only fixed point based MP3
player that qualifies as "fully compliant" accuracy.

At that point I decided to hack on madplay and see if I could improve its
performances without loosing accuracy, and I finally got it to go beyond
splay. Many of my changes have been already integrated into the current
madplay release. Therefore I'm not supporting splay anymore, but
advocating for madplay instead.
