It was actually really cute. I was trying to video two kittens having a full-on kitten battle on top of my hound dog. He normally doesn't care about much, but i think because i was watching, he warned them. That's what this is.
Recording of a warning signal for passing trams with passing tram in the background. Recorded at svingeln tram stop with iphone and enhanced in audacity.
Full siren test (with a couple of gaps) including the announcement for each siren and two separate sirens. There's a perfect delay as the sound bounces around the city creating an almost digital sounding delay effect for the announcement and reverb for the sirens.
halloween is not necessarily the time to aim for being. . . On trend, heh heh heh heh heh! an alternative take with less effects and an almost hacking laugh at the end.
I made this as a near ultrasonic sms signal. Created and edited with audacity, filtered with glame bandpass filter. If you hardly cut a pure tone, you introduce a whole lot of other frequencies to the signal at the cutting point. To avoid this after the cutting you need to filter the whole thing with a bandpass filter to ensure you have as little other frequency content as possible. It will audibly soften the start and the end of the sound. That's what i did here.
Recorded with audacity 1. 2. 6, then normalized, echo (. 03,. 5), pitch (b to g#/ab, down, -15), delay (10,. 1, 10). Klaxon made using sony acid music studio 8 and sony sound loops.

An approximation of a 3-toned engine powered/blower stationary air raid siren so powerful that it has to be set on a hill at least 2 miles from a population center. Based on a chrysler engine powered siren.
Inspired by a drawing posted on airradsirens. Com some time ago, a huge siren that is a hybrid of a thunderbolt and a hurricane siren, supercharged by a large industrial air compressor. You do not want to be anywhere close to this beast when it goes off!.
Mechanical outdoor siren recorded at a public park in bettendorf, iowa, united states. Attack (wavering) mode. The steady mode went on for several minutes so i just faded it out.
