Every now and then I'll be playing a track, and will have to adjust the BPM of the next track in order to adequately beat match it for crossfade purposes. Occasionally doing so will cause the next track to have an obnoxious "stutter" effect during playback, that goes in and out in relatively steady intervals, though not directly evenly on a beat.
Depending on the type of song, and the amount of BPM change, this stutter can be more or less apparent; But it's completely obvious and obnoxious to my inside my headphones.
I've even run into situations where this problem doesn't occur at all, even when the song's speed is lowered/raised significantly more than usual. (> 30-40 BPM difference).
What could be causing this stutter, and what can I do to mitigate it?
