W3C Audio Working Group Updates 2025
by Hongchan Choi, Google, co-chair of the Web Audio WG
The Audio Working Group advanced two key specifications in 2025. The Web Speech API was transferred from the WICG, with Chrome shipping its implementation and Firefox beginning theirs; spec work focused on on-device recognition and TAG privacy feedback. For the core Web Audio API, the AudioContext interrupted state was specified and entered a Chromium Origin Trial. The group also initiated a new Playout Statistics API and continued collaboration with the Web Performance WG on high-resolution time in worklets.
