How can i remove multiple parts of audio in 1 command with Ffmpeg?

Question

Im trying to cut multiple parts of audio with ffmpeg, i was able to find a working result (for video ) for a single filter : ffmpeg -i input.avi -vf "select='1-between(t,20,25)', setpts=N/FRAME_RATE/TB" -af "aselect='1-between(t,20,25)', asetpts=N/SR/TB" output.avi

How can i adapt this code for a multiple filters? For example if i want to remove fragments from 10to20, 50to60 etc.

Thank you

You can combine several between intervals, as shown here: https://stackoverflow.com/questions/50594412/cut-multiple-parts-of-a-video-with-ffmpeg . Just copying the command from this link:

ffmpeg -i video.mp4 \
       -vf "select='between(t,4,6.5)+between(t,17,26)+between(t,74,91)',
            setpts=N/FRAME_RATE/TB" \
       -af "aselect='between(t,4,6.5)+between(t,17,26)+between(t,74,91)',
            asetpts=N/SR/TB" out.mp4

Answer 2

I was able to reach the result i want with this command : ffmpeg -i input.mp3 -af "aselect='not(between(t,10,16)+between(t,20,50))'" output.mp3

Copying the video to a new file and deleting the audio while doing so is the quickest and easiest technique to remove or delete audio. This method is straightforward because you don't have to re-encode the movie while you're at it. The command line to accomplish this is provided here. ffmpeg.exe -i videoWithAudio.mp4 -c:v copy -an videoWithoutAudio.mp4 -c:v copy copies the video track into videoWithoutAudio.mp4 -an tell FFmpeg to not copy the audio
