Notch

Okay, here's something else I'd like to do.

I have a constant hum in my recording, which I've determined to be about 120hz. I can use Audacity to eliminate that hum nicely. But it would be very convenient if I could use dMC to do the same thing, just notch out that frequency. Possible?

Don't know if it would help, but try a conversion to the same kind of file you have (all as source) and use the Graphic equalizer from the DSP effects .

I'd wonder though where the hum is coming from during the recording. Is it feedback by any chance?

[Aweberman]

Not feedback. The hum is from my computer, the power supply maybe.

I've tried the Graphic Equalizer, but it doesn't affect the right frequency. The hum is very specifically at 121 hz. Whatever frequency the slider to the left of 130 on the equalizer is, it isn't that. I tried turning that down all the way and it had no effect.
