Federal Signal Touchmaster Delta siren

Did you use gtaivaud to import the new sirens? for me whenever I do it, it corrupts the file and the sirens don't play correct (either there is a pop at the end, or all you hear is a series of popping sounds for priority siren, or both).

Eitherway, any way you could incorporate the full scan mode siren from Touchmaster instead of just the last part of it?

Tourman, I do use the GTAIVAUD tool. The issue with modifying the sirens is that GTA IV is very touchy about the file size. It doesn't seem to matter so much the sound quality of the file as the size. So you could have a 44khz WAV file and import it, and as long as it was short enough and the other sound files in the IVAUD weren't too big, there wouldn't be an issue. A standard Wail tone is about 5 seconds start to finish, so there you usually have the biggest file out of the sirens. The yelp file should be less than a second long, because GTA IV will loop it properly if you have edited the start and end points correctly, same with hyper yelp. What I'm getting at, is that in order to use a longer siren tone when you already have a 5 second wail loop, you have to seriously drop the audio quality. Anything less than 22khz IMO sounds pretty horrible, very lo-fi, otherwise you end up with the popping sounds. Also, if you're using Audacity, be sure to open up the WAV file after you've exported it, sometimes if you save it incorrectly it will tack on a few seconds worth of silence, this will ruin the IVAUD if you don't catch it before you put the file in and create the popping.

For these reasons, along with the fact that Ultra HiLo can be programmed to be used as an individual tone on the real life Touchmaster(And is by a local department here), I have only included it instead of releasing the Scan tones demo'd on the Federal Signal website. If I do release a Touchmaster with the full scan for the POLICE_WARNING loop, it will have to be lo-fi and TBH, it will sound pretty horrible.

For a side note, there's a plethora of sounds that the Touchmaster Delta can generate if you use the proper amp with it, it's a fairly flexible siren. Some agencies prefer to use the scan, some prefer the individual tones. Take a look on youtube for an extended clip of someone messing around with the Touchmaster and you'll see what I mean. I'm not saying you didn't know any of this, I'm sharing this with you just in case it's why you were asking about the scan tones. Cheers!

Also, Thanks Dhruv, I'm glad you like it :)

Lol I made the same siren: http://www.lcpdfr.co...er-delta-siren/

However, mine was slightly slower than yours as mine was custom.

Yes, yours was the inspiration for mine, SC. I really liked yours but it was too loud for me, I like to run a police scanner while I play and I could not hear it over the siren! Also SC I'd like to apologize to you, publicly, as the original one I released contained your airhorn and ambulance_warning tones. I was brand new at modding GTA IV and did not stop and think that there were other wav files in the IVAUD that were custom, I was just thinking "Oh good I don't have to export the IVAUD to start replacing the sirens."

Whether or not you noticed I don't know but once again, my apologies. Every mod since then I've been sure to start from an original GTA IV file before modding it.

Thanks for the explanation. I kinda figured GTA was very touchy about sound files but wasn't sure.

First off, great siren. It sounds really low in game, is there a way to make it sound louder?. I can barely hear the siren while playing.

I'll see what I can do. All the files have been normalized to 0db, so if they get any louder they will start losing quality and start clipping.

Oh alright, didn't know that you had to keep it at a certain sound level to keep from losing quality.

could you put the car download link plz
