Mute specified sections of an audio file using ffmpeg

Question

I have a JSON file containing regions that I want to mute in a given audio file. How can I process the audio file to mute the file between the listed sections?

Answer 1

Thanks to @aergistal , it worked for me:

command line:

ffmpeg -i input.mp4 -af "volume=enable='between(t,1,2)':volume=0" output.mp4

nodejs fluent ffmpeg:

ffmpeg('input.mp4').audioFilters("volume=0:enable='between(t,1,2)'").output('output.mp4')
