I've been working on a C-based open source sound engine as part of a book project and wanted an approachable way for people to try it out without having to build anything.

Through the magic of emscripten (which I'm totally amazed by) and miniaudio (which has given me new life late in my development career), and a smidge of vibe-coded HTML/JS (web-dev is not my jam), this page will let you try out the tooling.

I gave a lightning talk on the ASCII notation at ElixirConf EU last month here:

There's a work-in-progress tutorial for the notation used in this tool at:

https://octetta.github.io/pulp/doc/learn.html

and a long-winded YT video of me showing a bit at:

I'll be showing this stuff off at the Audio Developer Conference in Tokyo June 2nd 2026.

If you're there and you're an audio developer (I'm not), I'd sure like feedback and guidance.

Oh, one other thing, a side-project that I showed here last month (k-synth) IS embedded here but that documentation is yet to be written.

You can read about that project at:

https://github.com/octetta/k-synth

and there's also a web-UI for that tool to learn the weirdo-API-ish notation here

Have fun, be nice.
