Default Is there a way to find a duplicate waveform so I can remove a sound?

I am editing old podcast episodes where I used to do this sort of forced laugh. It's a quick rush of breath and it creates a nearly identical waveform throughout my recording.

Is there a way reaper can find that same waveform elsewhere and either mark or silence it?

I have a feeling this is a big ask. I apologize about my ignorance of DAW capabilities.

Thanks!

I don't suppose this is even possible in the way you are intending to do this.

I am assuming the same thing. However, I do know that using Reafir, I can build a "noise profile" using the Subtract mode (which helps me silence white noise and such), so I thought something might exist that was more robust to do what I want to do.

Yes it seems fairly impossible just now.

But (and this is a stab in the dark!) would this help?

1. Use Reafir or whatever to build a profile of one instance of the offending sound
2. "Subtract" this from the whole waveform
3. If you are right this should produce periods of near silence that may be easily visible.
4. Mark these as regions, UNDO the correction and go back to delete the unwanted sections.

This might well be a really dumb idea - if so I apologise in advance!

spectral peaks are helpful as the sound should have a distinctive colour pattern so you can hunt them down.

nearly 20 yrs when this was all fields i did a college talk on comparisonics that finds sounds ( www.findsounds.com ) 'similar to X' - i think samplitude used it - and there was folk asking for it to be in reaper..


funny - the website is exactly the same as it was in 2000.

Worth trying at least! My result? Not good. I tried it on a small snippet, and the waveforms simply don't match well enough, proving the sounds are very different, even though they look the same. It will work with one laugh, but not the next because of minute shifts.

I have a feeling this is impossible! Need a human brain to identify laughter. Great thought experiment though, thanks!

Yes I feared as much. The only solution I guess is to train yourself to laugh identically in future...😊
