Ah yeah dataviews, but you still need to convert from json to those and that takes about as much overhead, plus they're much harder to deal with complexity-wise being annoying single type buffers and all. For any other language it would work better, but because JS mainly deals with data arriving from elsewhere it means it needs to be converted every single time instead of just maintaining a local copy for thread comms.

You don't necessarily need to have an intermediate JSON representation. Many of the built in APIs in Node and browsers return array buffers natively. For example:
const buffer = await fetch('foo.wav').then(res => res.arrayBuffer())
new Worker('worker.js').postMessage(buffer, [buffer])
This completely transfers the buffer to the worker thread, after which it is detached (unusable from the sending side) [1][2].
