Web Audio API changes in Chrome 36
With the release of Chrome 36, Google are continuing their move towards the standardised version of the Web Audio API that the W3C are developing. This is great news for developers who want to write Web Audio applications that will run everywhere the API is supported, but it’s a slightly painful since it means some breaking changes to the API in version 36 of Chrome (the current stable version). If you’re a developer, and haven’t been following development versions of Chrome, now’s a good time to go and have a look at your existing applications and make sure they’ll still work.
Chris Wilson, editor of the W3C Web Audio spec, and developer evangelist at Google, has written up a handy guide with all the things to look out for.
Dub delay effects with the Web Audio API
I wrote a blog post on how to create dub delay effects using the Web
Audio API. It’s fun effect that uses cycles in the Web Audio graph,
the interface with the
<audio> tag, and a
delayNode. Go and have a
play and let me know what you think.

Integration of Web Audio with WebRTC
As well as using the Web Audio API to generate sounds, we can also use it to process the audio from video and audio elements, as well as the audio captured from a microphone or other input source. Here’s several short examples that show you how to use this new interface.

-The Web Audio API - From Node/Express to Your Browser
A toolkit for quickly creating interfaces that can be hooked up to Web Audio experiments. Nexus UI provides a variety of knobs, slides and control surfaces that can control Web Audio parameters or OSC messages. It’s similar in someways to Charlie Robert’s interface.js, so take a look at both projects if this sounds like something that would be useful to you.
SuperCollider is easy and so can you!
Developer and musician Callum Gunn has started a series of tutorials on SuperCollider. SuperCollider is a musicians programming language with some similarities to the Web Audio API in its approach, but with a longer history. It’s really interesting to read Callum’s posts to learn about how to create interesting effects in both environments.
