Evosynth: Interactive Genetic Algorithm Sound Synthesis in the Browser!

Imagine a modular synth with 10s of modules that could be instantly wired up at random. Imagine then being able to combine or breed different circuits, or to create multiple variations of a circuit with subtle wiring changes. That's basically what evosynth does.

To be more specific, EvoSynth is a sound synthesis system which uses an interactive genetic algorithm to search the space of all possible configurations of a set of oscillators and filters. It is based on an idea I first experimented with back in 2000 with a system I called AudioServe. You can read all about that system here: AudioServe.

Run it on your own server

• Put the website folder on your server.
• edit the file website/assets/js/app_launch.js to reflect your settings.
• it probably works without the API back end, but...
• to allow saving etc. of circuits, edit ebsite/api/inc.php to reflect your server

build the minified library into the website folder

(yeah grunt etc. is better I am sure)

./build_evosynth.sh

the unit tests require mocha

npm install -g mocha

mocha tests/
