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.
