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

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:

Hints for the Installation
audioread to load audio files.
📝 Note that older releases of
soundfile (prior to 0.11) do not support MP3, which will cause librosa to fall back on the
If you're using
conda to install librosa, then audio encoding dependencies will be handled automatically.
If you're using

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
