[LAU] Are RT-patches needed anymore? (Was Re: >= 2.6.27 RT ETA?)

[Raffaele Morelli]

I think it depends on what kind of audio work you are facing to.

5.3 ms latency is not good if you do monitoring from software, so for
non-prof use almost everyone can live with 5.3ms latency.

But recording a vocal track could be a little drama, because latencies > 5ms
are really audible and from the headphones/monitor it sounds like singing
within an empty barrel of oil.
