i think that it was already said here, but...
the problem is that the sounds are too much "muffled", not only in the engine sounds, but every sound related to the car is muffled
thats why skids and crash sounds are too low, looks like the entire LFS sounds have only one channel, so if you change only one sound you change all of them together
i think thats not a hard thing to fix, i belive that this test patch was just to see how we will react with the new sounds, our feedback will help scawen to put the sounds on the right way
that is why important to not spam here saying things like " the sound is bad" "the bf1 is crappy"...
let's say something construtive to help the development of the sounds
sorry for the crap english hehehe
