With FFmpeg, it's able to manipulate audio or video files.
Here shows an example to cut up mp3 into specific duration.
ffmpeg -i <some-video.mp3> -ss 00:00:22 -t 00:00:32 <cut-up-some-video.mp3>
-ss is the start position.
-t is the duration (not the end position).
The command above brings that of 00:00:22-00:00:53 (32 sec), instead of 00:00:22-00:00:32 (10 sec).
The official documentation on its options is here.
