Or do it in one command: ffmpeg -i input.mp3 -to 1.20837 -c copy output_01.mp3 -ss 1.92546 -to 3.51778 -c copy output_02.mp3Īs in the segment muxer command this also uses stream copy.Manipulating a video with Node.js itself would be extremely hard, so instead, we are going to use the most popular video manipulation tool: FFmpeg. Using these options will omit the silent segments but is more work to make the commands: ffmpeg -i input.mp3 -to 1.20837 -c copy output_01.mp3įfmpeg -i input.mp3 -ss 1.92546 -to 3.51778 -c copy output_02.mp3 Note the use of -c:a copy which enables stream copy mode so your MP3 does not get re-encoded to avoid generation loss. You could perform a Bash loop on the output files, use silencedetect to find these segments, then delete/move them if you want to script that process.

You will need to delete the silent segments. See ffmpeg -h filter=silencedetect.Įxample output using awk: $ ffmpeg -i input.mp3 -af silencedetect=d=0.5 -f null - |& awk '/silencedetect/ ' Note the default minimum length for silence is set to 2 seconds, but it can be adjusted. Get silence with the silencedetect filter: ffmpeg -i input.mp3 -af silencedetect -f null. You can do this manually with ffmpeg, and of course it can all be scripted if you prefer.
