[Discussion] (near) real-time splitting?

Since spleeter (and demucs, for that matter) are running at faster than 1x on my CPUs, I would love to be able to play the resulting stems ASAP. But the output files are written all at once at the end, and not as streams.

Is there a way to force spleeter (or any other stem software) to dump their putput inmediatly?
Even using the pythin API, I can't see anything obvious.
