I will try using your code, but take a look at that:
Siren Public: (getting called on each /siren cmd

Код:

public Siren(playerid)
{
        new Float: pPos[3][2];
        GetPlayerPos(playerid, pPos[0][0], pPos[1][0], pPos[2][0]);
        pPos[0][1] = -1935.770019;
    	pPos[1][1] = 228.789993;
    	pPos[2][1] = 34.156250;
    	new tempSiren = 0;
    	if(siren[playerid] == 0)
		{
    	    for(new i=0; i<MAX_PLAYERS; i++)
    	    {
        	    if(IsPlayerConnected(i) && !IsPlayerNPC(i))
        	    {
   	                //GetPlayerPos(i, pPos[0][1], pPos[1][1], pPos[2][1]);
           		    soundID_siren[i] = Audio_Play(i, 1, false, true, false);
           		    //Audio_SetVolume(i, soundID_siren[i], 0);
           		    SendClientMessage(i,0xFFFFFFAA,"Siren started volumu 0");
                }
		    }
		    tempSiren = 1;
		    //return 1;
		}
        else if(siren[playerid] == 1)
		{
		    for(new i=0; i<MAX_PLAYERS; i++)
    	    {
        	    if(IsPlayerConnected(i) && !IsPlayerNPC(i))
        	    {
   	                Audio_Stop(i,soundID_siren[i]);
					SendClientMessage(i,0xFFFFFFAA,"Siren stopped for you");
                }
		    }
		    tempSiren = 0;
		    //return 1;
		}
		siren[playerid] = tempSiren;
    	return 1;
}

The next public getting called each 0.1 seconds. It should set the level of each audio(for now there is only one audio(audioID_Siren), but there should be more.

Код:

public AudioUpdate()
{
    new Float: pPos[3][2];
    new string[256];
    for(new j=0; j<MAX_PLAYERS; j++)
    {
		if(siren[j] == 1) // check if soembody has his siren On
		{
            pPos[0][0] = -1935.770019;
            pPos[1][0] = 228.789993;
            pPos[2][0] = 34.156250;
            //GetPlayerPos(j, pPos[0][0], pPos[1][0], pPos[2][0]);
            for(new i=0; i<MAX_PLAYERS; i++)//
            {
        	    if(IsPlayerConnected(i) && !IsPlayerNPC(i))
        	    {
        	        if(IsPlayerInRangeOfPoint(i, 100.0, pPos[0][0], pPos[1][0], pPos[2][0]))
        	        {
        	            GetPlayerPos(i, pPos[0][1], pPos[1][1], pPos[2][1]);
        	            new distance = 100 - floatround(floatsqroot(floatpower(floatabs(pPos[0][1] - pPos[0][0]), 2) + floatpower(floatabs(pPos[1][1] - pPos[1][0]), 2) + floatpower(floatabs(pPos[2][1] - pPos[2][0]), 2)), floatround_ceil);
        	            format(string, sizeof(string), "Distance: %d", distance);
        	            SendClientMessage(i,0xFFFFFFAA,string);
        				Audio_SetVolume(i, soundID_siren[i], distance);
        				//Audio_Resume(i, soundID_siren[i]);
        				//return 1;
        	        }
        	        else
        	        {
                       Audio_SetVolume(i, soundID_siren[i], 0);
                       //Audio_Pause(i, soundID_siren[i]);
                       //return 1;
        	        }
        	    }
        	}
		}
    }
    return 1;//the value what function returning
}

Maybe you misunderstood what should the code do.
The siren should be heard in the positions:

Код:

pPos[0][0] = -1935.770019;
            pPos[1][0] = 228.789993;
            pPos[2][0] = 34.156250;

siren[playerid] = 0; On player connect.
