(Alternately, I read something once about our perception of audio being delayed by ~100ms so that it synchs up with our perception of vision

If such a delay does occur it is considerably less than 100ml as that kind of latency would be very noticeable playing a musical instrument.

Is it possible that there is a delay for one-off unanticipated events, but the feedback loop we form between perception and playing is much tighter? I definitely have a hard time playing anything with much more than 5ms audio buffers myself.
