License: AGPL v3 Build Status npm version

A JavaScript library for music/audio signal analysis and processing for both real-time and offline use-cases. The core of essentia.js is powered by Essentia C++ library back-end using WebAssembly along with a high-level Typescript API and add-on utility modules. ie, Now you can run a extensive collection of music/audio processing and analysis algorithms on your web-browser or Node.js applications with ease-of-use. essentia.js also provides additional modules for easy-to-use configurable feature extractors for some selected features and helper classes for visualizing common music processing features directly into your HTML web page using Plotly.js library.

You are also most welcome to contribute to essentia.js.

NOTE: Currently under active-development, some of the algorithms are not yet manually tested on the JavaScript front. Please submit the issues at https://github.com/MTG/essentia.js/issues.
