Remove background noise in CoolEdit:
select a portion of dead air with just background noise and do Effect->Noise Reduction then click "Load Profile" (r something like that)
click ok, then undo the change made -select the entire sample and do noise Reduction agan, click preview and slide the slider from low to high and find the right balance between noise and muted sound!
P.S. if you are trying to remove something more substantial try phasing... see if you can cancel something out by phasing it out (sometimes producers use techniques to create depth or make some sound more dominant -- u can reverse them to remove material)
I.E. you have some intrument on the right chanel which happens to be out of phase from the left and delayed by 20ms so if you phase it you push the signals into phase and they cancel eachother out when you convert to mono using 1/2 and 1/2 for r/l channel mixing
or you phase it and push the vocals just close enough into phase that they stand way out from the original
depending on when it was made and by who you can remove most pop background music with techniques that involve phasing -- in fact they have some generic plugins that do it for you, but I'm not sure on the results
once you're done trying to phase the signal until the vocals are louder than anything else, use a little compression
(cool edit has a visual compressor mode you can use to kill low amplitude samples while retaining the high amplitude ones - compressor/limiter/whatever)
Good infos?
gimme my money bissssh!
