If JACK and its clients take one minute to process
a three minute song this is "faster than realtime"
Sure, but there's another meaning of realtime in the context of low or
zero latency. I was thinking about hardware buffers and the
impossibility of absolute realtime, more so faster than realtime
operation. If you can have more than impossible.
Perhaps when making a joke in future, I should put JOKE: in the
subject line!
