I am trying to remove a repeating noise, like a metronome or similar, from a recording (which was apparently accidentally introduced in post-production and not noticed). I have a basic understanding of Audacity, and have tried ‘Noise Reduction’ but it didn’t seem to have any success. The noise in question sounds a little like the default Windows mouseclick, and occurs every ~10 seconds. Is there an effective way to remove this using Audacity?
The zoomed-in waveform is here:
As you can see, it’s on one stereo channel far more than the other but is present on both.
