I have an audio recording in wave format of a face-to-face interview. Throughout the recording the television can be heard in the background, and at some points makes it very hard to hear my grandfather. I tried the noise filter, but even when the slider is set to low it tends to distort the voices, makes 'em sound like they’re underwater.
I ran Audacity’s analyzer on the noise, then tried to fit a FFT filter to the profile, but the range for the FFT is so large that I can’t adequately match the curve.
Yes, I’m very inexperienced with all this, so any pointers would be appreciated. Even if I can’t remove the background tv noise, I would like to be able to reduce its volume in the playback.
