: Given that metronomes are aimed at helping people when playing music, the timings really don't need to be perfect. A millisecond timer should do fine provided it is coupled properly to an absolute time source so the workload of sound and <s>fury</s> GUI doesn't interfere. (On the other hand, a timer on the scale of a second — usually the most available on the system — is definitely not sufficient.) –[[User:Dkf|Donal Fellows]] 08:11, 11 September 2011 (UTC)
:: What I was trying to get at with the point about timings is that you can't allow the work involved in display or audio updates to cause the timer to drift. That seemed the obvious intent of the "separate processes" wording. Certainly, the timings don't need to be perfect; <2ms jitter is probably unnoticeable, but that amount of jitter should hold true comparing events 600 seconds apart as well as 250ms apart. --[[User:Short Circuit|Michael Mol]] 18:14, 11 September 2011 (UTC)
