[TriLUG] Sound Processing

[Jim Ray]

Wouldn't a single pole high pass at 800 Hz slam 60 Hz into the noise
floor?

I'd use something like Cool Edit myself. It has been 15 years since I
last designed an analog filter in the field.  Everything has gone
digital.

Not my vacuum tube guitar amp, though ;-)

Jim

The analogue notch filters are really sharp. You can't 
acheive anything nearly as sharp with high/low pass. If 
you've got a single frequency, then notch is the way to go.
I don't know how sharp the FFT notch filters are.
