You need little or no digital audio expertise to get started. Author Boris Smus introduces you to digital audio concepts, then shows you how the Web Audio API solves specific application audio problems. You’ll not only learn how to synthesize and process digital audio, you’ll also explore audio analysis and visualization with this API.
- Learn Web Audio API, including audio graphs and the audio nodes
- Provide quick feedback to user actions by scheduling sounds with the API’s precise timing model
- Control gain, volume, and loudness, and dive into clipping and crossfading
- Understand pitch and frequency: use tools to manipulate soundforms directly with JavaScript
- Generate synthetic sound effects and learn how to spatialize sound in 3D space
- Use Web Audio API with the Audio tag, getUserMedia, and the Page Visibility API
Boris Smus is a front-end engineer working for Google Chrome Developer Relations, specializing in mobile web and web audio. Before Google, he was a Human-Computer Interaction researcher at Carnegie Mellon, and a software engineer at Apple.
