For immediate release
https://www.w3.org/ — 17 June 2021 — The World Wide Web Consortium (W3C) announced today that Web Audio API is now an official standard, bringing music and audio creation and manipulation to the Web.
Focussed on sound creation (rather than merely the playback of recorded audio), the Web Audio API provides a rich set of modular building blocks which web and app developers can combine to create a wide range of applications, including: auditory feedback in user interfaces, musical instruments, soundtracks and effects for entertainment and gaming, teaching, spatial audio for AR and VR, online audio editing apps, crossfading and compression for in-car music management, and audio analysis and visualisation.
With the API standardized and deployed as a royalty-free feature in Web browsers and other devices and platforms, both on desktop and mobile, creating sound with the Web Audio API has become a dependable, widely deployed, built-in capability, eliminating the need to install plugins or download separate applications.
Web Audio is used in many applications including: SoundCloud, Mozilla Hubs, Firefox Mixed Reality, Ableton, Google Meet and Stadia, SoundTrap, Amped Studio, BandLab, BeatPort, Soundation, Leimma & Apotome, and Spotify.
"The development of the Web Audio API to the point of it becoming a W3C Recommendation represents a huge effort from developers, audio experts and audio artists across industry and academia. A major contributing factor in the success of the API has been the support from the user community who have engaged with the spec and developed some incredible work", said Matthew Paradis, Audio WG co-chair. "The founding of the annual Web Audio conference has increased the reach of the API and provided a platform for academic, creative and scientific use of the WAAPI. Finally the enthusiasm of browser vendors to commit their time to shaping and implementing the API has made this a very rewarding process. I hope that this engagement will continue as we develop future enhancements to the API".
In contrast to most native audio applications, the Web Audio API naturally lends itself to creation of collaborative and interactive artworks online, where instead of a passive audience, people can actively interact with the artists and each other, using nothing more than the browser on their computer or mobile phone.
The W3C Web Audio Working Group has benefitted from the shared developer experience of the global Web Audio community over the last six years, exemplified by the annual Web Audio Conference series and the Web Audio weekly newsletter.
Together, the Working Group and community have already started work on Web Audio API v2. This will build on and enrich the first version of the API, adding more complex and much-requested features which were insufficiently developed to be included in the first version of the API.
Web Audio API joins the many W3C standards that define an Open Web Platform for application development with unprecedented potential to enable developers to build rich interactive experiences, that are available on any device and environment.
The mission of the World Wide Web Consortium (W3C) is to lead the Web to its full potential by creating technical standards and guidelines to ensure that the Web remains open, accessible, and interoperable for everyone around the globe. W3C well-known standards HTML and CSS are the foundational technologies upon which websites are built. W3C works on ensuring that all foundational Web technologies meet the needs of civil society, in areas such as accessibility, internationalization, security, and privacy. W3C also provides the standards that undergird the infrastructure for modern businesses leveraging the Web, in areas such as entertainment, communications, digital publishing, and financial services. That work is created in the open, provided for free and under the groundbreaking W3C Patent Policy.
W3C's vision for "One Web" brings together thousands of dedicated technologists representing more than 400 Member organizations and dozens of industry sectors. W3C is jointly hosted by the MIT Computer Science and Artificial Intelligence Laboratory (MIT CSAIL) in the United States, the European Research Consortium for Informatics and Mathematics (ERCIM) headquartered in France, Keio University in Japan and Beihang University in China.

Eleven years ago Mozilla pioneered the first experimental implementations of real-time audio processing in web browsers. We've been innovating in this domain ever since, and we are very pleased to see the Web Audio API become a W3C Recommendation.
With the addition of AudioWorklet’s direct audio sample manipulation, the Web Audio API is now a viable foundation for a broad range of use-cases and applications. Existing native code bases or highly custom processing algorithms can now be deployed on the Web to build fully-featured digital audio workstations, state-of-the-art VR experiences, or even physical modelling of acoustic instruments, delivering on the vision of our early experiments and building a better internet.
For nearly ten years Soundtrap has been working to democratize music creation and the Web Audio API has been at the core of our product since the beginning. Our goal has always been to make music and storytelling more accessible and collaborative, and Web Audio has been key to removing the barriers of installed desktop software and making audio production available to anyone with a web browser. We are proud to be a part of the Web Audio community and are excited to now see Web Audio recognized as the official W3C standard for audio on the web.Björn Melinder, Senior Staff Engineer, Soundtrap, Spotify
