Anyone know of some software that can discriminate between music and
voice, and then mute or attenuate the computer's audio output until
music comes back? This would be great for internet radio like Yahoo
Launchcast to block audio ads and rap. It would be even better if it
could filter a traditional radio broadcast fed to the computer's audio
input and silence all the blab. One could then listen to background
music while studying or otherwise concentrating without interrupting
his/her train of thought.

Thanks in advance
