Using Inverse Phase for Noise cancellation

[admin]

Heres something I had heard before but never tried. Will someone at teh Institute or outside try this, if havent done before already:

You can completely remove background noises if you have a clean recording of just the noise... You invert the phase of that clean noise recording, and mix a loop of it back into the source, it will totally nullify that sound leaving a clean track. This could be used for eliminating buzz from lights, generators, refrigerators, etc.. a little toying with it to get a seamless loop would be involved, and getting it perfectly aligned where you are mixing it in too, but given the proper time spent, it is truly amazing. If you've never heard the results of this before you'll be floored the first time you hear it
