Looper

A script for repeating music seamlessly and endlessly, designed with video game music in mind.

Installation

This script requires Python 3 to run, along with the NumPy and mpg123 packages. Once you have Python 3 installed, and this repository cloned or downloaded, you can install any needed packages using the following command:

pip install -r requirements.txt

This program also requires the external library mpg123, which is available here: https://www.mpg123.de/download.shtml

Usage

Looper is run from the command line as follows:

python3 loop.py track.mp3

If track.mp3 is a valid .mp3 file, then Looper will find as good a loop point as it can, and will then play the song on repeat, forever. (The program can be terminated using Ctrl+C.)

Limitations

At this point, Looper only supports .mp3 files. If you would like to see support for other audio formats, such as .ogg or .flac, let me know - or, better yet, feel free to send a pull request!

Looper currently requires an extended period of time (about 20 seconds) where the song already repeats itself, in order to confirm the precise loop point. If the song does not repeat, or it repeats less than that (or not at all), then it will loop, but it may do so at strange points (such as repeatedly looping over a few seconds.) If there is a song that you think Looper should be able to handle but find it cannot, please feel free to contact me (or, again, to fork this repository and improve upon it.)

You can’t perform that action at this time.
