Another sound plugin: http://depot.javispedro.com/nit/64/pa65.so

This one tries to minimize buffer underruns (choppiness) by resampling to a lower, dynamically calculated frequency.

It's mostly a fun thing to watch (Weeeeeeeeeeeeeeeeeeeeeeeeeeeeeeelcooooooooooooooo omeeeeeeeee to Maaaario Kart), but if you enjoy slowed down sounds more than frequent pauses, it might be useful for you.
