Hot on the heels of 0.12.4b, MAD 0.12.5b is now available with even more performance improvements.
Just for the record, here's a 3min22sec 192kbps mp3 decoded in a 233MHz StrongArm SA-110 running NetBSD:

mpg123 is the (not too good) fixed-point verison I did for the NetBSD package system. It's included here purely for a timing reference.
So overall pretty much a 30% improvement in the last four months (from 0.12.0a) on this specific platform. Well done!
