I know there's a ton of different fire alarms out there but I'm looking for the one that is consistenetly noisy & blaring al the way through, presumably from the newer strobe appliances they use in public schools. I'm NOT looking for voice-sampling, "whoop", "wee-wooo-wee-woo" or bell-ringing alarms, nor am I looking for composite ones. The closest thing I could find out of the 27 I got from searching "fire alarm" was this, but again its synthetic.
I'm also hoping someone will capture a gradual doppler effect. What I mean is slowly coming towards the source of the sound so it changes gradually. A sample over a minute long and up would be awesome.
Hope you can help. Thanks!
There would have to be considerable (+20mph) relative movement between source of the alarm and the listener for there to be a noticeable Doppler effect.
There is a good example of Doppler effect here ... http://www.freesound.org/samplesViewSingle.php?id=28426

It sounds like a klaxon or hooter. You could try using those words in a search.
I got one good result with "hooter". Klaxon was pretty much the opposite of what I was looking for. Thanks, though.

[It's even possible to calculate the speed of the vehicle from the amount of pitch shift, or vice versa: create an artifical doppler effect on a sound if the speed of the hypothetical souce is known ... http://en.wikipedia.org/wiki/Doppler_effect#Analysis
To be honest, I barely know what the doppler effect is. I'm thinking of what happens when you slowly approach and go past the source within a relatively slow walking distance, probably no more than 5-10 feet between source and starting/stopping point. I have a school's fire system in mind, so there'd probably be more than one source to consider which makes thing a bit more complicated.

That would be all amplitude (volume) rather than doppler which is a pitch change.

What sound did you end up using? And what was it that you liked about it?

It was this one:

There isn't anything I really "like" about it per se, it just sounds sort of close to what I'm looking for, at least for the first minute and a half or so. The sound I'm looking for, though, is I guess higher pitched and this siren did not come from a standard school fire alarm. Its hard to describe, but this sample is contstant up until the fade-out, which is the kind of fire alarm sample I'm looking for: loud, noisy, electronic and the same from start to finish.

That's the one that I thought you were talking about. I have created a version of that same sample with the wind noises electronically filtered out. Are you interested in that new version? Also, I could easily alter it to give it a higher pitch, if that would help. Let me know.
Again, I'm looking for a real life recording but I'd be happy to hear your version aswell

Here's the filtered version without most of the wind noise:

Let me know if that works for you.
Unfortunately, its not what I'm looking for. I'd be fine with white noise, wind and even background chatter if it was the sample I'm thinking about. Thanks for taking your time to do that, though
