Re: Detect and Match Sound?

["Steve ][" <sc-ii@hotmail.com>]

I like the idea of having a real glass break detector "do the work"
and let the computer determine what to do next. I think matching
waveforms might actually be harder than I first thought.

I looked around and that one appears to be much cheaper than most
items, I wonder what that does that its competition does not (or vice
versa)?
