good front-end for FLAC and WAVPACK.
I have had problems used APE in foobar2000...
The only advantage over popular FLAC that MAC files are
~2% smaller in side.
And there's a cost: MAC is very slow and less supported.
If you need small size no matter of speed, use OptimFrog which is also less supported by soft/hardware.
It took to long to release it. Good it came at all :-)
