Recent and Future Evolution of the Web Audio API
summary
Repository activity shows 358 commits since WAC 2018 and about 139 pull requests merged this year, leaving nine hard issues; work focuses on tightening under-specified behaviors rather than new features. Audio Worklet gets precise Web IDL and GC-safe argument semantics, MediaStreamAudioSourceNode now picks a stable track, getValue and getFrequencyResponse return current-time values, convolution and channel-count changes cut CPU by switching modes, and an async v2 path is proposed because some impulses take ~15 ms per impulse and can freeze the UI.
