The ProcessedMediaStream object is on the main thread. The processing
happens in a Worker.

We could also offer a processing API that happens on the main thread. You'll
be subject to main-thread latency then, and liable to glitch.

We will probably offer a main-thread API to generate a stream by injecting
data periodically (initially audio samples, but could be other kinds of data
too). That would be a lower-latency way to generate a stream from the main
thread (lower latency than posting the data to a Worker which is driving a
zero-input ProcessedMediaStream), but would also be liable to glitch if
you're not buffering up data very far. Doing real-time things on the main
thread is just risky :-).
