A Shell script for splitting or slicing large mp3 audio files.
The idea of this program is to take an mp3 file e.g a music 'mix' downloaded from youtube or another site and split it with a timestamps file found on youtube or another site, you might want to adjust it to the format.
- FFmpeg
Install these dependencies with your package manager.
For example in Ubuntu and the rest of Debian based systems.
sudo apt install ffmpeg
- Download the script
wget https://raw.githubusercontent.com/diegosanchezp/mp3split/master/mp3split.sh -O ~/.local/bin/mp3split && chmod 755 ~/.local/bin/mp3splitThis will put the shell script in the folder ~/.local/bin/ and can be accessed via terminal as a binary file.
Also the command above can be executed to update the script.
You must have the folder ~/.local/bin/ added to your $PATH variable, if you don't want to, install it to another folder.
Usage:
mp3split [OPTIONS] inputaudio tracklist
Options:
-s: do a simulation without writing anything to disk.
-h: print this help.
-e extension: set output extension, if extension is equal to "" keep extension of input file.
The script will output all the splitted files in the
current/working directory.The script will output all the splitted files in the current/working directory.
The tracklist format is like those found on youtube comments of music videos.
'timestamp' 'Name of song'
Example
0:00 Xtract - Audiotool Day 2016
3:55 Alison space echo
Errors thrown in color red while processing each split are from ffmpeg.
Given the mp3 audio file testsong.mp3 and the tracklist tracklist.txt located in ~/test/ which is also the current/working directory.
tracklist.txt
0:00 Xtract - Audiotool Day 2016
3:55 Alison - space echo
7:25 Volt Age - Volt's Theme
13:12 Lucy in Disguise - Southbound
18:05 Lucy in Disguise - Echoes In Time
23:15 HOME - Flood
26:53 De Lorra/Augustus Wright - Let Us
31:09 bl00dwave - Encounters
33:51 Emil Rottmayer - T.I.M.E ( Part 2 )
40:12 oDDling - Early Bird
43:22 hello meteor - at last light
Run the command
mp3split testsong.mp3 tracklist.txtIt will output information about the created split files to stdout

And the splitted files
3,1M Alison - space echo.mp3
2,4M bl00dwave - Encounters.mp3
5,8M Emil Rottmayer - T.I.M.E ( Part 2 ).mp3
1,5M hello meteor - at last light.mp3
3,4M HOME - Flood.mp3
4,9M Lucy in Disguise - Echoes In Time.mp3
5,2M Lucy in Disguise - Southbound.mp3
3,1M oDDling - Early Bird.mp3
5,3M Volt Age - Volt's Theme.mp3
3,5M Xtract - Audiotool Day 2016.mp3
Example with argument -e
# keep extension of input file
mp3split.sh -e "" input.ogg tracklist.txt
# creates .ogg
# force specific output extension
mp3split.sh -e "wav" input.mp3 tracklist.txt
# creates .wav
# default extension ".mp3" is preserved
mp3split.sh input.mp3 tracklist.txt
# creates .mp3Be careful with the filenames with a slash '/' this might declare the filename as directory followed by a name as you can see in the example below there it was an error thrown by ffmpeg.
De Lorra/Augustus Wright - Let Us.mp3: No such file or directory
For this case the script wont stop it's execution and it will continue to process the other splits.
I took as inspiration Lukesmith booksplit script
