120 ac and vehicles
4-6 sounds per object
400-500 sounds
FMOD is a very robust program, once learned can do insane realism.
For any one orrson its a lot of work. It might take 1 day+ per object
Some of the objects don’t exist in running condition to get authentic sounds from. Very few, if any, wwii sims have all authentic sounds. Most all games use simulated sounds.
Challengers files is the best chance. I hope his brother is still working on tweaking them.
That said, I’m finishing a video that exploits exterior engine sounds. While only using a few ac, they sound pretty damn good, and they are default sounds. I can hear fmod work, and impressed with what it really did to the game with 360 degree stereo sound.
Sometimes it has to do with how one mixes their sounds in game. Things that are too loud mask sounds you really should hear. Default is a flat line mix.
To know whats wrong one must first know whats right. Very few have this experience, it takes a team. Some may be fooled thinking real sounds are not right. Its a massive project.
