Python module for audio and music processing
A python package for music and audio analysis.
See http://librosa.github.io/librosa/ for a complete reference manual and introductory tutorials.
What does librosa do? Here are some quick demonstrations:
- Introduction notebook: a brief introduction to some commonly used features.
- Decomposition and IPython integration: an intermediate demonstration, illustrating how to process and play back sound
The latest stable release is available on PyPI, and you can install it by saying
pip install librosa
Anaconda users can install using
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
(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
pip list you should see
librosa now as an installed package:
librosa (0.x.x, /path/to/librosa)
Hints for the Installation
audioread to load audio files.
soundfile does not currently support MP3, which will cause librosa to
fall back on the
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
manually. Please refer to the SoundFile installation documentation for details.
audioread and MP3 support
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 ffmpegor
apt-get install gstreamer1.0-plugins-base gstreamer1.0-plugins-ugly
- Linux (yum):
yum install ffmpegor
yum install gstreamer1.0-plugins-base gstreamer1.0-plugins-ugly
brew install ffmpegor
brew install gstreamer
- Windows: download binaries from this website
For GStreamer, you also need to install the Python bindings with
pip install pygobject
