It will not qualitatively improve the feedback. 1 second may be quantitatively
50% faster than 2 seconds, but it remains qualitatively infuriatingly slow. It
is not worth the risk to screw up audio buffering, IMO.
Anything slower than 300 ms is annoyingly slow. Anything slower than 100 ms is
noticeably poor even if acceptable. Human can sense audio delays from rougly
40 ms. Unfortunately, those values are much too short for generally safe
underflow-free/stutter-free VLC audio playback.
We have already been through this a few years ago already. There are no known
good ways to amplify sound on Windows, except when the replay gain is known in
advance (which it almost never is).
