The Web Audio API enables synthesizing audio in the browser. Audio operations are performed with audio nodes, which are linked together to form a modular audio routing graph. Multiple sources — with different types of channel layout — are supported. This modular design provides the flexibility to create complex audio functions with dynamic effects.
The first version of Web Audio API, implemented in all modern browsers, recently reached Candidate Recommendation; work has started on the next version.
