Audio recording needs low latencies but *not* real-time. The most
I would challenge this statement.
This you say,
"The scheduling requirements of JACK to achieve sufficiently low latencies
And in the first sentence of your quote you state exactly what I wrote
:) Low latency is not the same as realtime, specially hard realtime. And in the future please honour common nettiquette by only quoting the part which you reply to.
But still, keep all relevant parts when you reply :). In this case, the original sentence was not that JACK only needs low latencies (in general) but that JACK was a major reason why the rt kernel was needed and developed. In audio editing, you need _guaranteed_ low latencies because you might want to process the recorded sounds (use effects), mix them with the original and also play them back to the musicians while recording. Without this guarantee you may have a fast system (with low average latencies) but not a real time system. Therefore, you either go for low latency, set small buffers and risk buffer overflows, or you choose high latency and you don't have professional audio anymore.
