Table of Contents
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.
The latest stable release is available on PyPI, and you can install it by saying
python -m pip install librosa
Anaconda users can install using
conda install -c conda-forge librosa
Building from source
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 following commands from a python console:
import librosa librosa.show_versions()
This should print out a description of your software environment, along with the installed versions of other packages used by librosa.
📝 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 python -m pip install -e librosa
git clone https://github.com/librosa/librosa.git python -m 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.
📝 Note that
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:
apt-get install ffmpeg
apt-get install gstreamer1.0-plugins-base gstreamer1.0-plugins-ugly
yum install ffmpeg
yum install gstreamer1.0-plugins-base gstreamer1.0-plugins-ugly
brew install ffmpeg
brew install gstreamer
For GStreamer, you also need to install the Python bindings with
python -m pip install pygobject
