Re: Sound recognition (not voice) - recording instances and duration of

["Robert Green" <ROBERT_GREEN1963@xxxxxxxxx>]

I'd just use something like CoolEdit and record for twelve or twenty four
hours.  If you start at 12AM then you'd have a good map of exactly when it
went off - you'd just read off the time tick marks.  With modern large hard
disk drives,  you can record quite a bit of audio on a PC.

We did a similar thing when we were concerned that the dog was barking in
the crate when we were out.  You get a mostly flat audio file with a few
small bumps.  It's very easy to zoom in on the little "bumps" that will show
in the audio file.  I am sure a wa-wa siren has a pretty distinct looking
signature.

If you're looking for proof you can take to court, you might have to get a
little more sophisticated.
