Diveplane you are one the experts in DCS sounds. I have some questions and remarks on the Mig 21BIS sounds. I discovered that the Mig21 uses general engine sound files from the Main Sounds file directory in DCS world such as EngineGE.wav, EngineJet.wav and more from this directory. The Mig21 engines sound files are located in the CoreMods en Mods directory (Mig-21BIS/Sounds/Effects... etc).
However these files are unfortunately not used when flying the Mig. (at least on my PC). Above all when checking the sdef files in the Mods en CoreMods directories you will see that the link is not correct. wave = "Effects/Aircrafts/Cockpits/Mig21AroundEngine". It reverse to the sound files in "cockpits" dir and not to the sound files in the "engines" dir.
Of course I changed, adjusted the sdef files and moved the sound files. Whatever I did, it never changed anything in the sounds when flying the Mig. When I temporarily moved the general jet sound files in the main sound dir from DCS world, I discovered that the Mig uses these files.
I am not an expert but I change found files from time to time in DCS. So overall I know how change the sound files and adjust to sdef files. Perhaps the Mig21 (because it is beta) uses other links for sounds (lua!!!??? I really don't know).
Maybe you can bring me some light in the darkness.....:helpsmilie:
