remove feedback from recording

[frank stamm]

I recorded a stand-up comic friend of mine doing a live performance. I recorded onto a digital minidisc. The PA was giving some feedback when he got loud at all.

Is there any way to remove feedback from a live performance with Cool Edit?

Thanks for the help,

You can probably remove the feedback, but it will impinge on the quality of the guy's voice. See, if you remove the frequency that the feedback was at, then you also remove that frequency from the guy's voice. But even then, it'll only work if the feedback was a constant frequency - if it varied in pitch a lot, then it'll be almost impossible to remove.

Anyway, if you want to try it: take the track into Edit View>Effects>Noise Reduction. Use the Help to walk you through the steps. You essentially highlight a very short segment of the feedback alone (without any voice at that point), and get Noise Reduction to sample the frequency. Then you save the sample. Then you apply the sample to the whole wavform, and it'll remove all of the frequency you sampled from everything in the wav.

Had Noise Reduction, particularly the Hiss reduction, work wonders for me in CEP. Id give it a shot.
