This program (only works on a A500 or 2000 sorry 1000 owners!!) cuts off the high frequency anti-aliasing effects used by the machine and also turns the power led on and off (only the led is affected on a 1000). What this means to the layman is a distinct sound improvement, just try using it with Sonix or another program that uses a lot of sound. It usually improves sound no end but it is not very effective with long, poorer quality sound samples (10Khz or under). Just drag this icon to another disc or use it from CLI (even better in the startup-sequence).
