This is based on a previous Call Sign Mod that I worked on to make it sound better in game --
Simply put all folders into you saved games directory C:\Users\NAME\Saved Games\DCS.openbeta\Sounds\Speech\ENG\Common
Put the lua. file here > F:\Program Files\Eagle Dynamics\DCS World OpenBeta\Scripts\Database
NOTE: YOU WILL NEED TO PUT THE LUA FILE IN AGAIN AFTER EVERY UPDATE AS IT GETS CANCELLED OUT. THE SAVED GAMES FOLDERS ARE FINE (for now)
Not perfect, but adds a lot to the game imho. enjoy.
I simply took the audio files and put them in Audacity for editing. Now they sound closer to the 'comms' that you hear when speaking to tower, wingmen...etc.
