BarMusComp: Encoding songs with linear and nonlinear compression methods to reveal structure

Hello, and welcome on this repository!

This project aims at compressing all bars in a song, and studies the compressed representations of every bar to infer its structure. It is related to my PhD thesis [1].

This repository contains code for the NTD, PCA, NMF, and Autoencoders (developed in PyTorch), as presented in [2].

This project is an extension of the toolbox as_seg [3], which computes the segmentation of an autosimilarity matrix.

It can be installed with pip using pip install barmuscomp.

This is a first release, and may contain bug. Comments are welcomed!

Software version

This code was developed with Python 3.8.5, and some external libraries detailed in dependencies.txt. They should be installed automatically if this project is downloaded using pip.

Tutorial Notebook

4 tutorial notebooks are available in the folder "Notebooks", and present the different compression methods on the song 'Come Together'.

They are only present if you downloaded the project from git (e.g. https://gitlab.inria.fr/amarmore/barmuscomp), and are not available in the pip version (which is in general not accessible easily in the file tree).
