How to cut an audio file on Linux
I had an .m4a file and I wanted to cut a one-minute chunk starting at second 156. Turns out you can easily use
ffmpeg for this.
WARNING: Argument order matters here. Specifically, the
-t 60 has to be after the
-i input.m4a specifier to indicate that the output file should be at most 60 seconds.
ffmpeg -ss 156 -i input.m4a -t 60 -acodec copy out.m4a
That’s all folks!
