• Essentia

Essentia is an open-source C++ library for audio analysis and audio-based music information retrieval released under the Affero GPL license.

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.
