Hi
Does audacity have tool for finding and deleting particular sound?
I have lot of files with same “beep” in every of them and I’m looking for easy way tp\o remove it more or less automaticaly
No it doesn’t, though “beeps” are often clearly visible in the track spectrogram view: https://manual.audacityteam.org/man/spectrogram_view.html
If the beep is a single frequency, you may be able to remove it using the “Notch filter” effect, without doing too much damage to the rest of the recording: https://manual.audacityteam.org/man/notch_filter.html
