How can I replace multiple parts of audio with generated beeps?
I tried next command:
-filter_complex "
[0]volume=0:enable='between(t,10,15)+between(t,20,30)'[main];
sine=f=800,
pan=stereo|FL=c0|FR=c0,
volume=0:enable='between(t,0,10)+between(t,15,20)'[beep];
[main][beep]amix=inputs=2:duration=first"
It successfully replaced parts between 10 - 15 seconds and 20 - 30 seconds
but the beep keeps playing till the end of the audio.
I think you also must make the beep silent after t=30:
volume=0:enable='between(t,0,10)+between(t,15,20)+gt(t,30)'
