Federal PA-15A Siren 1.0.0

The early Federal Signal electronic sirens were always some of my favorites.  I look forward to seeing a preview of the siren in-game.  Again, it's a shame that GTA V mutes the entire audio section if a single track is too long for its liking.

Be sure to download the latest version of OpenIV and run it as administrator

2 – Find audio file you want to edit by going into x64 folder
3 - Then click on audio folder where you should see one folder and two files.
4 - Click on the sfx folder and then select and click on the file: RESIDENT.rpf
5 - Upon opening the RESIDENT.rpf file, you should see 16 items shown. One of them is the vehicles.awc file.
6 - Right click on vehicles.awc and export to openFormats (.oac) to any folder you like (e.g downloads folder).
7 - Extract the vehicles folder (containing the four audio files of the siren) from the .rar file to the same folder that was exported in.
8 – Afterwards, go to edit mode in OpenIV. There will be a warning upon editing mode so be careful.
9 - Import the .oac file by either draging the file to OpenIV or go to new and click on Import openFormats to select the .oac file then click on open.
10 - Click on ok
11 - Click on edit mode again (if you are in edit mode already) to exit edit mode.
12 - To ensure everything works, click on the vehicles.oac file twice and click on either 0x1C98C4D5 or 0x144C8602 to see if the files were successfully replaced. 
13 - Exit OpenIV and play GTA V.

Happy? 

Thank you. I'll try to record the gameplay video of the new ambulance siren later on. I'm surprised that my PC managed to record in GTA 5 without heavy performance issues. That shows you that this game is really well optimized for even systems like mine. 

Followed your very detailed instructions, however now I don't have any sirens (even for the police vehicles). My vehicles awc was already modified with a new police siren and walter's train sounds mod, would this clash with any of these?

I'm not too sure on what happened. Please tell on what exactly happened when you replaced the ambulance sirens. 

Installed as per your instructions, but no sirens at all on any emergency vehicles. I'll try again in case I missed something.

Are some of the sirens' length longer than the original ones? If so then that'll explain on why they've been muted. :<

If any of the siren sounds in V are longer than the original ones (and sometimes even if they're the same length it will do this), the entire audio archive will mute itself, unfortunately.
