The README presents madmom as a Python library for audio signal processing with a focus on music information retrieval, including reference implementations of MIR algorithms.

Source: https://github.com/cpjku/madmom

What it supplies: The README presents madmom as a Python library for audio signal processing with a focus on music information retrieval, including reference implementations of MIR algorithms.

Useful for: - Use reference implementations of MIR algorithms for research on music audio.
- Install it with pip for use in Python projects.

First action: - Install the prerequisites such as numpy.
- Install with pip install madmom rather than from GitHub zip files.
- Read the online documentation linked from the README.

Prerequisites and limits: The README says Python 2.7 or Python 3.5 or newer is needed along with prerequisite packages; that wording is old and a current Python version should be checked against the documentation.

- Model and data files are non-commercial and share-alike; commercial use needs contact with the authors.
- The installation prerequisites in the README are dated.

Source-documented: the package has two licences. Source code is BSD, but model and data files are CC BY-NC-SA 4.0, so they cannot be used in commercial products without permission as the README describes. Check which files you use.

Written from the README text only. Statements are as the README gives them; nothing was installed or run.
Based on opening, licence and installation README text only; the references and later sections were not read. Nothing was installed or run.
