Web Audio Weekly


It's been a while since I put a newsletter together, so I have a bumper issue for you. Part of my excuse is that I've been working on an album of ambient music that I recently released. It's available to listen for free/pay-what-you-like, let me know what you think and thank you as always for your support. I always love hearing from you, so do hit reply and say hello.

Rust Web Audio API


Rust Web Audio API is a pure Rust implementation of the Web Audio API, for use in non-browser contexts. It has two goals: to provide a cross-platform audio library for command line apps, games and other applications and, via NodeJS bindings, a library that can be used both in and outside the browser using shared Web Audio code. A WAC paper and talk explain the context and give more details.

Kurku - Body tracking web MIDI controller


Kurku is a browser-based application that allows you to control MIDI devices with your body movements. Rather than use expensive and uncomfortable hardware, Kurku leverages a webcam and a browser to map body movements to MIDI CC messages.

In brief

Thanks to all of you for sending me great links to projects and posts, I've accumulated so many over the past months so here's a grab-bag of amazing things:

Autoplay Policy Detection


Firefox now has an implementation of the Autoplay Policy Detection standard, which allows developers to know whether a user has allowed auto-playing media (currently <audio>, <video> and Web Audio API) and react accordingly - perhaps by asking the user to explicitly start the audio.

AudioParam Visualization


Parameter automation in the Web Audio API is powerful, but it can be confusing. This site gives an overview of the usage of the various AudioParam automation functions and handy visualisations of how the parameters themselves change over time when automation is scheduled.

An Approach to Sound Synthesis with L-Systems


Learn about the maths behind Lindenmayer systems, generative systems that create complicated patterns by repeatedly applying simple rules, and how to use them to synthesise sounds.

Flutes, synths, a human voice – how should electric vehicles sound?


When the musician and sound designer Danielle Venne, of Made Music Studio, was asked to lead the design on the acceleration sound of the Nissan Leaf, she experimented with layering samples of woodwind instruments, flutes, clarinets and synthesisers.
