Realtime is not a hardware abstraction. It is implicit in the digital
audio datastream. Number of frames divided by frame rate yields a
realtime duration. If JACK and its clients take one minute to process
a three minute song this is "faster than realtime", just as my 24x CD
burner runs faster than realtime.
Is this really confusing you?
