I just did a quick check and you shouldn't even notice the amount of CPU
the VAD takes. The problem is most likely caused by floating point
exceptions of some sort, either NaN's, denorms, or underflows. I've
never encountered the problem, so it's likely specific to the kind of
data you process. Can you try pinpointing the problem a bit and then
send me a sample file?
