album-splitter

Use album-splitter to automatically split any audio file (youtube videos, albums, podcasts, audiobooks, tapes, vinyls) into separate tracks starting from timestamps. album-splitter will also take care of tagging each part with the correct metadata. If your file is on YouTube, you can download it automatically.

Common use cases covered:

  • music album on YouTube to download and split into tracks
  • full audiobook to split into chapters
  • music tape/cassette rip to split into tracks
  • digitalized vinyl to split into tracks

All you need is:

  • The file to split OR an URL of a YouTube video
  • Timestamps for each track, for example:
    • 00:06 - When I Was Young
    • 03:35 Dogs Eating Dogs

How to install

First time only:

  • Install ffmpeg
  • Install Python 3 (a version newer or equal to 3.7 is required)
    • Linux: apt install python3 (or equivalent)
    • Windows: Official webiste
    • MacOS: You should have it already installed or brew install python3
  • Open your terminal app
  • Create a virtual environment
    • python3 -m venv venv
  • Activate the virtual environment
    • Linux/MacOS: source venv/bin/activate
    • Windows: ./venv/Scripts/activate
  • Install album-splitter
    • python3 -m pip install album-splitter
  • You are ready to go!

After the first time:

  • Open your terminal app
  • Activate the virtual environment
    • Linux/MacOS: source venv/bin/activate
    • Windows: ./venv/Scripts/activate
  • Optional, update album-splitter:

  • You are ready to go!

Quick guide (from a local album)

  • Create a copy of the tracks.txt.example, rename it as tracks.txt
  • Open tracks.txt
  • Add your tracks timestamps info in this format:
    • <start-time> - <title>
    • A track on each line
    • See Examples section, many other formats supported
  • Run the script
    • Basic usage: python -m album_splitter --file <path/to/your/album.mp3>
    • More in the Examples section
  • Wait for the splitting process to complete
  • You will find your tracks in the ./splits/ folder

Quick guide (from a YouTube video)

  • Copy the YouTube URL of the album you want to download and split
  • Find in the YouTube comments the tracklist with start-time and title
  • Create a copy of the tracks.txt.example, rename it as tracks.txt
  • Open tracks.txt
  • Copy the tracklist in the file, adjusting for the supported formats
    • <start-time> - <title>
    • A track on each line
  • Run the script
    • Basic usage: python -m album_splitter -yt <youtube_url>
    • More in the Examples section
  • Wait for the Download and for the conversion
  • Wait for the splitting process to complete
  • You will find your tracks in the ./splits folder

Output Format

The format of the output tracks is the same as the format of the input (same extension, same codec, same bitrate, ...), it simply does a copy of the codec. If you want to convert the output tracks to a different format, you can do this using additional tools.

For example to convert from .wav to .mp3 you can use FFmpeg. Here is how you can do it on Linux/macOS. This or this might help for Windows instead. You can adopt such snippets to do other processing, such as changing the bitrate.

Examples

Downloading and splitting an album from YouTube

  • This is the album I want to download and split: https://www.youtube.com/watch?v=p_uqD4ng9hw
  • I find the tracklist in the comments and I copy that in tracks.txt, eventually adjusting it to a supported format for the tracklist
00:06 - When I Was Young
...
14:48 - Pretty Little Girl
  • I execute python -m album_splitter -yt "https://www.youtube.com/watch?v=p_uqD4ng9hw" and wait
  • Once the process is complete I open the ./splits and I find all my songs:
    When I Was Young.mp3
    ...
    Pretty Little Girl.mp3

These songs are already mp3-tagged with their track name and track number, but not their author or their album, since we have not specified it.

Splitting and tagging with Author and Album a local file

  • I somehow got the file DogsEatingDogsAlbum.mp3 that I want to split
  • I set the tracklist in tracks.txt (same tracks as before)
  • I execute python -m album_splitter --file DogsEatingDogsAlbum.mp3 --album "Dogs Eating Gods" --artist "blink-182" --folder "2012 - Dogs Eating Dogs"
  • The software will execute, it will split the album, and mp3-tag each track with the author and the album name I passed as a parameter (as well as track number and name). It will also put the files in the folder passed as an argument (instead of putting them in the default ./splits folder)

Supported formats for the track list (tracks.txt)

These are just some examples, find more in tracks.txt.example.

  • [hh:]mm:ss - Title
  • Title - [hh:]mm:ss
  • Title [hh:]mm:ss

To just see which data would be extracted from the tracklist use the option --dry-run.
