That's what I was saying.  As long as you get the feedback from your 
input in less than 70 ms you can't notice the delay, so a 32 ms audio 
buffer should be just fine as far as the feel of the feedback latency

Right because gap = wrong tone and high pitch noise for those 3 ms, and 
you definitely detect that as a pop or scratch sound.
