As I said, I didn't measure it, so it could be lower... I really can't tell past a certain point. How would you measure this?

A 2 channel recording with the close mic'ed switch on one channel, and whatever the switch is triggering goes
to the other channel.  Then measure in a DAW ( Audition )

You can get the arduino to drop whatever it's doing and respond *immediately* to your button press if you use the hardware interrupt pins. The bulk of the latency would then be determined by your button debouncing

hmm, interesting

... you would have to use buttons that stop bouncing very quickly to achieve less than 5ms latency.

no, just trigger on the first signal and ignore any bounces for the next 10mS or so
( sounds clever huh.....Matthias told me)
