" summary

Begins as a 2009 Google 20% experiment implemented in WebKit and evolves into a cross‑browser API, building a fast multithreaded convolution reverb with impulse responses to standardize room sound, refactoring a monolithic design into a modular audio node graph, adding AudioParam automation (2011), oscillator and media element/WebRTC nodes, and enabling live input via MediaStream (Sept 2012); Chrome ships behind a flag in 2011 and later by default, Mozilla implements in 2012–13, and AudioWorklet arrives as the modern processing model.
