These are fake siren noises i made in logic by using es p. The warnings are in the following order: caution (three pulses), alert (steady), attack (wailing), large fire (hi-lo), evacuate (hi-lo/alternate wail). These don't conform to any signal guidelines and must not be used for anything other than a mere sound effect.
Here's audio of an actual eas "immediate evacuation" alert sent via the cap protocol, which is eas via internet, which then activates radio and tv stations ( in the usa)this particular alert was due to wildfires enchroaching on the town of silverthorne, colorado.
Two tone siren that is used by all emergency service vehicles, including police, ambulance and fire department (in 2012) in the netherlands. This is not a recording of an actual siren, but generated by a synthesizer at the exact two frequencies that the siren consists of. For a realistic result it is suggested that you mix this with other background sounds and add your own doppler, echo, panning and other effects to suit your needs.
This is essentially a bass guitar with distortion with three layers of notes, merged together to make a "siren" of sorts. It can be used as a fire alarm, or maybe an alarm on a spaceship or ufo.
A stereo wav recording from a zoom h1n during a thunderstorm today. One siren picks up followed by several more producing a convincing stereo image. I have done a basic bass roll-off, but have left it otherwise untouched. If you have a spectral editor you can probably clean out more of the noise, but i couldn't do so and keep the sirens sounding good.
Original file name: wah whistle suspense bees - 30 september 2012specs: demo at 120 bpm, stereo, 48000 hz, 24 bit, wav formatdescription: created the sound using the thor polyphonic synthesizer in propellerheads reason. Sounds weird when played in isolation, but sounds decent when played as an arp or melody. I have included the "c" note spanning 7 octaves in case the samples need to be loaded into a sampler. Sample pattern: demo | c0 | c1 | c2 | c3 | c4 | c5 | c6. Contact (pm) me if you want any changes to this sample (please include freesound sample number 166169). You can use this commercially with proper crediting, but please let me know where and how you use it - seeing this used will really make me happy. :).
