[LAU] audio latency question

[andy baxter]

Hi,

I am thinking about a possible design for the second version of the 
position sensing drum pad I have been working on, and I have a question 
about latency. I am working around the assumption that 10ms latency is 
about the worst it can get before people start to notice it in practice, 
so I am thinking of building the pad in a way where the normal latency 
is about 1ms, but it degrades to between 10-15 ms in the very worst case 
(many simultaneous strikes and pressure variations across the pad). 
Allowing this level of degradation would make it possible (I think) to 
use an arduino rather than a faster processor, which would be nice.

So the question is, where does this 10ms figure come from, and is it a 
reasonable working value? I have picked it up somewhere but I'm not 
exactly sure where.

Thanks for any replies.
