Unfortunately, wmavoice has the same problem of AMR: the floating-point

Comparing my core duo with Mans' ppc box:

stddev:    0.16 PSNR:111.87 MAXDIFF:   10 bytes:   264014/   264014
stddev:    1.12 PSNR: 95.34 MAXDIFF:   58 bytes:   264014/   264014
stddev:    2.50 PSNR: 88.36 MAXDIFF:   98 bytes:   527906/   527906
