Dave Phillips <dlphillips@xxxxxxxxxx>: > Btw, additions and corrections are welcome. Hi Dave, maybe add the -I and -O options. They let you specify "systemic latency". When you route audio out of JACK's realm to process somewhere out there (physical signal processors or "the net" even) and then route back into JACK you get latency to deal with. An example for where that matters is Ardour which has to align outgoing and incoming audio. Real-world example is my ad/da that is connected via adat (in/out latency of 34 frames) and is used to bus audio through a hardware dynamics processor (in/out latency of 36 frames and then take it back into an Ardour signal path. With "-I 70" and "-O 70" Ardour's alignment is sample-perfect. The net can be audio source (collaborators on the other side of the world) or insert (networked ladspa box) in an Ardour signal route. Never tried it but -I and -O should give you perfect alignment just as well. Wolfgang
