Ok so In UP3 or your one of first version engine start sequence is different for most aircraft, right ? In your last sound mod version engine start sequence is the same for all planes. Basically when you put two planes for example A-20 and Bf-109 on the same runway engine start exactly the same in in both you can not spot difference
next BF-109 engine is too quiet compared to other engines, I raport this issue every version you released
Battelfield sound too loud
Ambient sounds are too loud, all explosion, cars ect. are to loud I don't know how to describe this it is to loud
And cannon sound is unrealistic Because the quality is not very good, I will say default cannons sound is much better because someone spend some time on mastering.
And At last
I don't know which version of your mod I have it was one of first If I will find time I can upload this for you
I love it
