So i have this file which is all talking people and beep sounds. The beep sound is always the same and i need to mark every place where it plays. It would be great if it's possible to do with Audacity. But i think i can only search for silence or sound above a certain dB level with it. Is there something i'm missing or do i need another app?
I know of no software that can do this for you automatically, however if the beep sounds is very distinguishable and it is possible for you to isolate its primary frequencies with an EQ, you may be able to make it drive a gate, which then in turn silence the track when there is no beep.
You then render a new wave file with this gated output and import that into same project, and use your existing search for silence/sound function to search for non silent parts on the new track.
