Notch filters
Wednesday, January 05 2011 @ 05:34 PM CST

I've been informed that a notch filter might be the solution to eliminating or reducing guitar hum. I'm willing to give it a shot, and find out what the difference is between a notch filter/band-stop filter and simply using EQ to kill frequencies.

Can anyone recommend a free or reasonable priced notch filter? I'm using Garageband '08 on 10.4.11.

A notch filter is a parametric EQ with a very high Q. So just take a good EQ and set one of the bands for 60Hz and crank the Q.

I'm not sure that I believe the respondent that you also need to kill the harmonics.

Here's a video that covers the Parametric EQ and Notch Filter in GarageBand. Jump to 5:43.


Hope this Helps!
