Global Sequencer


The Global Sequencer is created by Sound Designer Yuri Suzuki, as part of Hamamatsu City’s initiative to broaden and push the boundaries of sound design. 2021 is a year still largely affected by the Covid-19 pandemic, restricting the free movement of people and changing all our lives. In response to this situation, we present an interactive sequencer featuring sounds from around the world to create a sense of global connection.



There's been some renewed activity in the audiojs/web-audio-api project. It's an implementation of the Web Audio API in NodeJS. A complete implementation would be very useful for creating test suites that run offline, sharing audio code between the browser and server and creating stand-alone audio applications. There's additional background in the issues.

Any percussive sound can become a tonal instrument if you play it fast enough!

svemlr - mlr in the browser


A browser based version of the classic MAX/MSP live looping, sample-cutting environment. Unfortunately you'll need a monome grid to try this out, but the code is available if someone fancies adding a browser-based grid emulation.

Scale Navigator Dashboard


Explore scales, chords and learn how to modulate between them using these shape-based visualisations.



Cables is a programming environment for creating visual and sound art. Pieces are created by connecting operators together using cables. There's a large number of operators for creating 3D scenes but also some really interesting web audio examples.



The dsp.wags.fm API provides some useful DSP functions (such as spectral centroid, phase vocoding and noise filtering) via a HTTP API. This might be useful if you need to batch-process user generated content, particularly on devices that may not be able to perform the calculations fast enough.

OK Computer but everything is my voice


This is what you'll get, when you mess with us.
