Cell phone buzz

I'm editing an interview which has some of annoying interference from an incoming cell phone call. Anyone know the magic formula for EQing (or any other approach) for minimizing it? I can't seem to find the right frequency. Or is something altogether different going on?

I can't tell you exactly how to do it but look at Soundtrack Pro. I remember seeing a demo at NAB a few years ago and they were able to process out a walkie talkie that was squelching in the background, in that same demo they were also able to reduce and unwanted motorboat sound.

You might have some joy with a band pass filter, if it's different enough from the speech - it usually gets rid of some of the qualities of the interview record - in this case, it may make it sound muffled.

I'd try the noise reduction in Soundtrack Pro as a start. You find the bad sound in a gap between words. Highlight some of that and use Process/Noise Reduction/Set Noise Print. Then use Process/Noise Reduction/Reduce Noise and play with the settings. If it's a narrow spectrum sound, it can work OK. You can also play with the spectrum display option to visualize the noise and attempt to edit it out. View/File Editor Display/Show Spectrum.
