You can install those dependencies on a Debian/Ubuntu system using the following command:
sudo apt-get install build-essential libyaml-dev libfftw3-dev libavcodec-dev libavformat-dev python-dev libsamplerate0-dev libtag1-dev
In order to use python bindings for the library, you might also need to install python-numpy-dev or python-numpy on Ubuntu:
sudo apt-get install python-numpy-dev python-numpy
Install a scientific python environment first:
- ipython --pylab if you have matplotlib >= 1.3
- ipython --pylab=tk if you have matplotlib < 1.3
Note that you are advised to install python environment as described here, i.e., via homebrew and pip. You will most probably encounter installation errors when using python/numpy preinstalled with OSX 10.9.

brew install libyaml fftw ffmpeg libsamplerate libtag
Essentia does compile and run correctly on Windows, however there is no Visual Studio project readily available, so you will have to setup one yourself and compile the dependencies too. We will be working on Windows installer in the near future.
To build the documentation you will also need the following dependencies (you might need to run this command with sudo):
pip install sphinx pyparsing sphinxcontrib-doxylink docutils
Other useful dependencies:
pip install pyyaml # make sure to have libyaml installed first
You might need to install pip before, if you are on Linux:
sudo apt-get install python-pip
Once your dependencies are installed, you can compile Essentia (the library) by going into its directory and start by configuring it:
./waf configure --mode=release --with-python --with-cpptests --with-examples --with-vamp
NOTE: you must always configure at least once before building!
The following will give you a list of options:
To compile everything you’ve configured:
To install the C++ library and the python bindings (if configured successfully; you might need to run this command with sudo):
To run the C++ base unit tests (only test basic library behavior):
To run the python unit tests (include all unittests on algorithms, need python bindings installed first):
To generate the full documentation (need python bindings installed first):
Documentation will be located in doc/sphinxdoc/_build/html/ folder.
All built examples (including the out-of-box features extractors) will be located in build/src/examples/ folder, as well as the vamp plugin file libvamp_essentia.so. In order to use the plugin you will need to place this file to the the standard vamp plugin folder of your system (such as /usr/local/lib/vamp/ on Linux).
The 2.0.1 version of Essentia includes a number of pre-trained classifier models for genres, moods and instrumentation. In order to use them you need to:
