I'm trying to accomplish what I'm sure so many have done before, yet I'm not able to find anything of use when I've done my searches. 

What I want is to be able to manipulate values based on the audio input played on my pc. When I poked around with the beatdetector, that seemed to be something I could make use of but I need to be able to have a real-time audio input. Is this possible? Is there anyway I can set it to listen to my onboard sound card, or a mic input and generate those values?

All feedback is GREATLY appreciated.

Thanks.
