actually there is a plugin/application that does exactly that


But its not opensource...

what i was thinking, if you want to remove a buzz...that is something  
for a denoising tool.

Maybe spectral editing ??

Is there a spectral editing tool for linux ??

What i am actually missing is a periodic notch filter for mid and  
high frequencies (200 - 2500 Hz)

Have a good time
