XA tracks will desync at faster speeds

[Illeprih]

Possible solution could be to use a phase vocoder, possibly using short-time fourier transforms. That will esentially split the wave into components, then we could cull (n - 1) waves, stitch it back together, it lowers audio quality, but you end up with faster tracks with no change in pitch. It could eventually be used on SFX in general, to ensure some consistency at higher speeds.
