[mad-announce] MAD 0.12.4b available

[Rob Leslie]

MAD 0.12.4b is now available.

This version incorporates a number of performance improvements for all
platforms.

It also includes (untested) native fixed-point math support for the PowerPC
platform, contributed by David Blythe. Since I've made some significant
changes to the way the fixed-point math routines are maintained, I'd
appreciate feedback from anyone using MAD on a PPC to make sure I haven't
broken anything.

Finally, this version changes the way mixed short blocks are handled in
Layer III with respect to alias reduction, correcting another apparent
ambiguity in ISO/IEC 11172-3. Since mixed blocks are rare (many encoders don't
support them) this has until now gone unnoticed. Thanks to H.O. for reporting
this.

The source code release is here:

Winamp users should notice improved performance in the MAD plug-in:
