Madmom is a powerful audio signal processing library that focuses on music information retrieval (MIR) tasks. Written in Python, it is widely utilized by researchers and institutions for its reference implementations of common MIR algorithms. This blog will guide you through installing and using Madmom in a user-friendly way, alongside some troubleshooting tips.

Getting Started with Madmom

The first step to utilizing Madmom is ensuring that you have the necessary setup. Here’s a breakdown of what you need to do:

Prerequisites

• Python 2.7 or Python 3.5 or newer.
• Install the following packages:
  • Numpy
  • Scipy
  • Cython
  • Mido
• For enhanced audio input and FFT performance, consider installing:
  • Pytest
  • Pyaudio
  • PyFFTW
• If you need audio file support beyond .wav, install FFmpeg (avoid avconv if using Ubuntu Linux due to decoding bugs).

Installation Instructions

Madmom can be installed in two main ways: from the package or from source. Here’s how to do both:

Install from Package

The easiest method is through pip. Open your terminal and run:

pip install madmom

This command installs the latest code, trained models, and dependencies automatically. If you prefer to install it locally for your user, use:

pip install --user madmom

Install from Source

If you want to contribute to development, you can clone the repository:

git clone --recursive https://github.com/CPJKU/madmom.git

Then navigate into the folder and install:

python setup.py develop --user

Understanding the package structure

Imagine Madmom as an elaborate toolbox. Each folder within Madmom serves a distinct purpose:

• bin: Executable algorithms.
• docs: Documentation.
• madmom: Core Python package functionalities.
• madmomaudio: Audio file handling and STFT features.
• madmomevaluation: Various evaluation metrics.
• tests: Testing scripts.

Each of these sections contains tools (or functions) that you can pull out for different audio processing tasks, similar to how you might select the right tool from a toolbox based on the job at hand.

Running Programs

Once installed, you can run multiple scripts to analyze audio files. You can execute scripts in different modes (single, batch, or online) depending on your requirements. Here’s an example of running a single audio file:

DBNBeatTracker single INFILE

Troubleshooting

If you encounter any issues during installation or running the package, consider the following troubleshooting tips:

• Ensure all prerequisites are met and updated. Use the requirements.txt file for guidance.
• If using pip, try upgrading using pip install --upgrade madmom or reinstalling as necessary.
• Refer to the mailing list for community support.
