I've been looking around for some way to play a noise or audio file, when the network is sending/receiving data (or specify different sounds for the different operations). Something that will audibly play via the sound device and output to the speakers.

Heard of anything that would do something similar to this? I got the idea from my speakers, which are throwing out static sounds when I'm downloading big files, because of my WiFi card and the RF energy messing with the speakers.
