# microsound (prototype)
The main objective of the project is to provide an editor and built-in functions facilitating the generation of sound samples with code, as well as provide an example runtime for code-golfing projects (for js13k and the likes).
This project is more geared towards sound-effects synthesis than music generation or livecoding.
A secondary objective is to resurrect my [Algorithmic Synth](https://github.com/kchapelier/algorithmicsynthjs) project, although the state of the implementations of AudioWorklets is apparently still problematic.
This prototype works best in Firefox and Chrome (stable, not canary).
## Serious warning : Avoid using headphones with this and other DIY audio synthesis experiments. You could be one typo away from eardrum rupture.
