Hehe I know the picture he provides about Kazakhstan and its people is... not very correct
Regarding your sounds...
Well... Overall I have to say they are to loud and this makes the overall quality suffer a bit. A few of them have a kind of annoying echo. I know it should enhance the immersion and give the player the feeling to be inside a sub - but with a good card and EAX you actually dont need to add echoes to the sounds...
Another thing are the "Cargo_hyd". The sound is cool, but its never-ever a cargo ship! cargo ships are always slow and low in sound profile. I guess you mixed something up there?
I like the new Creak Sounds. Good job on this one!
The new engine orders are a nice idea. but there is a big error. he says "jawohl herr kapitän!" this is wrong, unless the player is a captain/kapitän in rank. and after that you can hear a "jawohl herr kaleun"... very confusing! oh and the loudspeaker thing...uhm... i cant say for sure, but i dont think the germans used them for orders like this. because the order was given in the same room where the engine-telegraph is. no need to inform the whole boat
the "ChE_K_Dive_planes_set_for_normal_dive.ogg" is very strange too. first you can hear a "Sir!" in a GERMAN phrase... uhm... no way, never ever! you will only find this in stupid hollywood movies with terrible syncro...
(note by the way: do not use sounds from crappy movies

)
and they talking about a water leak inside the sub...everytime you dive? mh...
Uhm ok. Ive checked the rest and I have to say they are nearly all "wrong" if you go for realism... but I have to say wow... you put A LOT of work in this and must have spent many hours doing this. Some very nice ideas (like the "identifying ship" sound when you hear him searching in the book... nice
But the most is actually garbage - at least for german speaking people - because it doesnt make sence. Im so sorry to say that.
I hope you dont hate me now...
