A python package for music and audio analysis.

Documentation

See https://librosa.org/doc/ for a complete reference manual and introductory tutorials.

The advanced example gallery should give you a quick sense of the kinds of things that librosa can do.

Installation

The latest stable release is available on PyPI, and you can install it by saying

pip install librosa

Anaconda users can install using

conda-forge

conda install -c conda-forge librosa

To build librosa from source, say

python setup.py build

. Then, to install librosa, say

python setup.py install

. If all went well, you should be able to execute the demo scripts under

examples/

(OS X users should follow the installation guide given below).

Alternatively, you can download or clone the repository and use

pip

to handle dependencies:

unzip librosa.zip
pip install -e librosa

git clone https://github.com/librosa/librosa.git
pip install -e librosa

By calling

pip list

you should see

librosa

now as an installed package:

librosa (0.x.x, /path/to/librosa)

Hints for the Installation

librosa

uses

soundfile

and

audioread

to load audio files. Note that

soundfile

does not currently support MP3, which will cause librosa to fall back on the

audioread

library.

soundfile

If you're using

conda

to install librosa, then most audio coding dependencies (except MP3) will be handled automatically.

If you're using

pip

on a Linux environment, you may need to install

libsndfile

manually. Please refer to the SoundFile installation documentation for details.

audioread and MP3 support

To fuel

audioread

with more audio-decoding power (e.g., for reading MP3 files), you may need to install either ffmpeg or GStreamer.

Note that on some platforms,

audioread

needs at least one of the programs to work properly.

If you are using Anaconda, install ffmpeg by calling

conda install -c conda-forge ffmpeg

If you are not using Anaconda, here are some common commands for different operating systems:

Linux (apt-get):

apt-get install ffmpeg

apt-get install gstreamer1.0-plugins-base gstreamer1.0-plugins-ugly

Linux (yum):

yum install ffmpeg

yum install gstreamer1.0-plugins-base gstreamer1.0-plugins-ugly

Mac:

brew install ffmpeg

brew install gstreamer

Windows: download ffmpeg binaries from this website or gstreamer binaries from this website

For GStreamer, you also need to install the Python bindings with

pip install pygobject

Citing

If you want to cite librosa in a scholarly work, there are two ways to do it.

If you are using the library for your work, for the sake of reproducibility, please cite the version you used as indexed at Zenodo:
If you wish to cite librosa for its design, motivation etc., please cite the paper published at SciPy 2015:
