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].
