It is a complex waveform. You cannot do it with simple
notch filters, no matter how many of them you have.
You need the DSP function where the noise waveform
is sampled and then removed. This is a built-in function
of Adobe Premiere (and Cool Edit before Adobe bought
it). I would have thought it was a rather common feature?
