Fantastic project ... and a few questions about javascriptmusic HOT 2 OPEN

Hi, thanks for the feedback :)

Regarding your questions:

1. The best approach here is to use AudioWorklet which is what I use in this project. AudioWorklet renders buffers of 128 frames and send to the audio hardware ( via a AudioWorkletNode ). This is the approach used in this project to obtain low latency and realtime playback.

2. The AudioWorkletProcessor has to be written in JS but it can call into WASM for rendering the buffer of 128 frames.

3. The heart of the code generating the audio in this project is the fillSampleBuffer method ( https://github.com/petersalomonsen/javascriptmusic/blob/master/wasmaudioworklet/synth1/assembly/index.ts#L173 ). This code of course takes into account that you should be able to control the notes from the outside and also use multiple instruments. In order to just make the simple basic example, you'd just make sure that your process method of the AudioWorklet calls into WebAssembly ( or even just does it in JS ) to something that just returns samples of a sine.
