RC 1.70.141503 : Jet sound pops in very late
New, NormalPublic


I have noticed, that you often can't hear the engine sounds of jets, even if you should be able to hear them.

I think i figuered it might have something to do with them going supersonic, as it seemed to work right when i limited the speed in the waypoints when testing.

Edit: nevermind that. it was just more subtil.

So i placed 4 jets passing me at 2km, 1.5km 1km and 0.5km distance at max speed.
See and hear for yourself.

especially good to see and hear is the part with the sonic boom. as soon as you hear the boom you should be able to hear the jet engine, but instead you hear it first 14sec later.

Tested the same with limited speed:
Audio poped in before the jets passed me, but still popped in. Not as bad as in the first example, but still not perfect.


Operating System
Windows 10 x64

My Sound setup:

especially the first 30 sec

did some more testing, and found out, that it might have something to do with jets moving in range.

sounds work right:
sounds don't work right

the only difference is the distance those jets started away from me. altitude, speen and the distance they pass me should be the same (within tolerance)
so if you want to test yourself, those are the setups i used:

(not working has 4x2 jets. the last two jets have the same distance than the working ones.
it is also possible to move the player 2km north in the not working mission, then the first 2 jets work as intended))
