So I had recently changed my audio siren tones and made my primary ELS Police sirens wail 3 and quick 3 i made my ELS Sheriff sirens Wail 4 and Quick 4 and in the process i had to mute some audio files to unmute all of my sirens which were as follows

Horn_01 which is the clown horn

Internal_Cabin_T- 

Siren 2 which none of my vehicles use and I have changed the ELS VCF Files to not use them

SIREN_PA20A_WAIL- again none of my vehicles use it and i changed the VCF's

 

All of these are muted and everything else is the same But while in game occasionally ill hear a constant tone playing that sounds exactly like a flatline. I don't know what could be causing this. please help

Your topic has been moved to GTA V Support, this is not LSPDFR related.
Please post in the correct location in the future.

So basically it sounds like another siren tone that is playing in the background? Or is it a horn?

 

Maybe you can check this video, it might help you with something:

 

I appreciate the video but I already know how to put sirens in the game. The sound doesn't sound like a horn or a siren. It sounds like a weird ambient flatline that will play in the background of the game and then it will fade as i drive away or get louder if i attempt to locate what the source but i have yet to find out what is causing it. Go to the 0.11 sec mark it sounds almost like that. Its not that loud as in the video but occasionally the game will make that sound sometimes.

 

Its not the police cars as all of them use this set of sounds in my ELS Files

 

-<SOUNDS>

<MainHorn AudioString="SIRENS_AIRHORN" InterruptsSiren="true"/>

<ManTone1 AllowUse="true" AudioString="RESIDENT_VEHICLES_SIREN_WAIL_03"/>

<ManTone2 AllowUse="true" AudioString="RESIDENT_VEHICLES_SIREN_QUICK_03"/>

<SrnTone1 AllowUse="true" AudioString="RESIDENT_VEHICLES_SIREN_WAIL_03"/>

<SrnTone2 AllowUse="true" AudioString="RESIDENT_VEHICLES_SIREN_QUICK_03"/>

<SrnTone3 AllowUse="true" AudioString="VEHICLES_HORNS_POLICE_WARNING"/>

<SrnTone4 AllowUse="false" AudioString="VEHICLES_HORNS_AMBULANCE_WARNING"/>

<AuxSiren AllowUse="true" AudioString="RESIDENT_VEHICLES_SIREN_WAIL_03"/>

<PanicMde AllowUse="true" AudioString="VEHICLES_HORNS_POLICE_WARNING"/>

</SOUNDS>

 

And my Sheriff vehicles use this set

 

-<SOUNDS>

<MainHorn AudioString="SIRENS_AIRHORN" InterruptsSiren="true"/>

<ManTone1 AllowUse="true" AudioString="RESIDENT_VEHICLES_SIREN_WAIL_02"/>

<ManTone2 AllowUse="true" AudioString="RESIDENT_VEHICLES_SIREN_QUICK_02"/>

<SrnTone1 AllowUse="true" AudioString="RESIDENT_VEHICLES_SIREN_WAIL_02"/>

<SrnTone2 AllowUse="true" AudioString="RESIDENT_VEHICLES_SIREN_QUICK_02"/>

<SrnTone3 AllowUse="true" AudioString="VEHICLES_HORNS_POLICE_WARNING"/>

<SrnTone4 AllowUse="false" AudioString="VEHICLES_HORNS_AMBULANCE_WARNING"/>

<AuxSiren AllowUse="false" AudioString="RESIDENT_VEHICLES_SIREN_WAIL_02"/>

<PanicMde AllowUse="true" AudioString="VEHICLES_HORNS_POLICE_WARNING"/>

</SOUNDS>

 

All of those Siren tones are custom besides the police warning and ambulance warning thats still stock like I said all the stock police siren tones SIREN_2 and PA20 are muted aswell is the clown horn and that internal cabin sound. I did that to make my file smaller because originally adding the sheriff tones muted it.

Update

I think i figured it out the park ranger vehicle was still using the old sirens! but the fact that i heard the noise in the city is weird when they were no where insight.
