The Siren Board

Well, the siren test, which was scheduled for today, has been canceled, due to bad weather. However, I do have a new recording to share with you. I programmed a Thunderbolt 1000T emulation on one of my synthesizers. I included emulations of the siren rotating, and even the blower running as the siren sounds. It's not 100 percent perfect, but here's an emulation of a 1000T sounding a three minute Alert signal.

I ran the audio signal through a set of speakers, so it would sound more authentic. This is supposed to sound like a 1000T about a half mile away. The startup is not exactly right, but I'm working on it.

really nice sounding, the tone almost sound the same as the real one. what synthesizer are you using for this?

I'm using a Yamaha Tyros2 right now, but I plan on reprogramming the sound on my Yamaha Motif ES6. On the Motif, I can create a much more realistic startup and wind-down, and I think I can make the overall tone more realistic. It will likely take me a while to figure out a way to emulate the Attack signal, because in order to do that, I would have to know how to make my own custom LFO waves on my Motif.

Here's a much better version of this emulation. It's in stereo, and it was recorded on my new Olympus recorder with my Soney stereo mic. It's in WMA format.

Nice recording, that sounds like the real thing! Good job!

Thanks for the compliment. If this were a real Thunderbolt 1000T, would the chopper be set to a level of about 4 to achieve this pitch? Also, most of our Thunderbolts have blowers that hum almost the exact same pitch as the one in this emulation. Would that mean that we have B series blowers?

I'm amazed! The windup sounds better than I expected. You got the acoustics just right on that. I'd try to add some sort of echo effect to the steady tone, though, since it seems sort of dry.

I've actually heard the steady tone on Thunderbolts sound dryer than that on days when the wind wasn't blowing much. I did add a bunch of reverb to the sound, so that's why the accoostics sound so close to the real thing. It's still not perfect though, and I plan on reworking it on my other synthesizer soon.

Wow, that is truely amazing.... that is a dead on sound of a T-bolt... even the rotation aspect of it sounds correct. Truely amazing work!!

I'd bet that the rotation is what makes it "dry". It just seems sort of a simple up-down, but the rotation volume is a bit different... I don't know how to explain it. Sort of a short moment at max volume, and more time at minimum volume on the other end.
