Book Description

Working with the Web Audio API is the definitive and instructive guide to understanding and using the Web Audio API.

The Web Audio API provides a powerful and versatile system for controlling audio on the Web. It allows developers to generate sounds, select sources, add effects, create visualizations and render audio scenes in an immersive environment.

This book covers all essential features, with easy to implement code examples for every aspect. All the theory behind it is explained, so that one can understand the design choices as well as the core audio processing concepts. Advanced concepts are also covered, so that the reader will gain the skills to build complex audio applications running in the browser.

Aimed at a wide audience of potential students, researchers and coders, this is a comprehensive guide to the functionality of this industry-standard tool for creating audio applications for the web.
