I get this rattle behind the voice sometimes when using audacity. It seems to always start about 2-3 mins into a recording. I have tried different mics. It doesn’t happen every recording but is annoying when it does! I cannot use noise reduction as the rattle seems to be generated only behind the voice audio.
The problem of “clicky” recordings on Mac sometimes requires the counter-intuitive measure of reducing the “Buffer length” in Devices Preferences.
As to rescuing the recording, there is no simple method. All I can suggest is zooming in, finding each glitch, selecting a small region around it and doing Effect > Repair.
You can use repair individually on each of the glitches, but that will take an eternity.
There is a DeClicker plugin for Audacity which does the all the repairs in one go, (it’s slow but much quicker than by-hand).
