This bash script allows you to split a long audio file into shorter files of any length, each with their custom name.
Usage from the command line:
ffmpeg-audio-split.sh <original_audio_file.mp3> <timestamps.txt>
This script has been tested on mp3 files, but should work with all audio formats compatible with FFmpeg
timestamps.txt format example:
00:00:00 00:02:04 name_of_file1.mp3
00:02:04 00:05:37 name_of_file2.mp3
All timestamps have to be in HH:MM:SS format. The name of each resulting audio file has to include its extension (in the case above, .mp3), or the script won't work properly.
