Noise cancellation program?

[Antoneo]

I was wondering if there is a program that takes in audio from a mic and then sends it 180 degrees out of phase to speakers/headphones. That would make a noisy environment slightly less noisy right?

That would be interesting, I have only seen expensive hardware for that kind of issue though.

Hrmm...this would be an interesting proggie.

Interesting, kinda like those Bose noise cancelling headphones.

Wouldn't it be simple enough to run your microphone into a stereo amplifier and connect one of the speakers backwards?

I think that latency would be a major problem....especially if the mic and the headphones were not very close together.

Peace,
will
