Hello,I am writing software for a psychology lab that needs to play sounds with sub-millisecond latency for one of its experiments. The original software the lab used runs on OS 8/9 and makes use of the old SndManager system. It loads all sounds into memory at the beginning of the experiment, and is later able to start the sounds with sub-millisecond latency. I have not been able to replicate with Core Audio the low-latency levels achieved with the old system. Is it possible to play sounds with sub-millisecond or even <5-10 ms latency in OS X? Is the "load all sounds into memory" approach still a good one?
i think you're confusing a number of different meanings of the word "latency". you should be a lot more precise about the performance/behaviour characteristics that you are looking for.
