well, of course 64 samples is only the HARWARE latency (and it corresponds to 1.5 ms @ 44100 Hz) ; "2 periods" regards software processing only (correct me if I'm wrong)
and here, "2.9 ms (64 smp)" meant : "when I use a buffer size of 64 samples on the HDSP, the global latency told by Qjackctl is 2.9 ms"
actually that is what i was talking about: when qjackctl tells me that i have a latency of 2.9ms, most users (i assume) tend to say: "oh cool, so i get a latency of 2.9ms!!"
i just wanted to make clear, that the numbers in qjackctl are only part of the truth.
unfortunately i haven't yet been able to test the latency of a system without pd (just wiring the inputs of the hdsp to the outputs via jack)
anyhow, the patch i use for latency-measuring can be downloaded from our cvs via cvs -d:pserver:anonymous@cvs.iem.at:/cvsroot/latency login cvs -d:pserver:anonymous@cvs.iem.at:/cvsroot/latency co pd
(compiled versions of zexy and iemlib1 are included in the cvs)
sorry for the confusion
me too.
