Hello, this is my first post on this forum. Thank you community in advance.
I use Audacity to master stereo studio recordings of acoustic instruments. I’m currently working on a recording by a student cello ensemble. In our best take, one of the players crashed their bow into something, probably a music stand. I usually can fix these things, but am struggling this time. Would someone please take a look and help me out?
bow click.aup3 (1.9 MB)
It extends across almost the entire spectrum, and lasts ~200ms, if you include the echoes 
IMO your only hope would be to overwrite the noise with copies of of nearby audio.
The result would be a less intrusive glitch, rather than an undetectable repair.
I overwrote the offending section with pure silence and on playback I couldn’t hear the tiny gap

Thank you both! The duration of the bow click is too long to set it zero because then I can hear the silence.

@Trebor That’s pretty good. How did you do it?
Completely silence the unwanted sound, as Waxcylinder did.
Then make copies of the ~100ms of audio either side of the silent gap, and use them to fill the gap. Overlap & crossfade, so rather like time-stretching.
@Trebor, you’re a pro! I’ll give it a try. Thanks!
It worked. Thank you so much!
