Thanks Devrim, but it doesn't seem work.
I increased the volume of each wav file with audacity using gain, making sure nothing clipped.
Flaps sound louder now, but wanting to isolate everything to only hear flaps, airbrake and gear, I added "OFF" to each of the Engine wav files and the wind files. Restarted DCS, now there's almost no sound in the cockpit. Deploying the airbrake now, I could hear no mechanical/hydraulic sound at all. Then I realised that AirBrakeIn and AirBrakeEnd files don't exist, only the flaps and Gear have these files. But is this the way it's supposed to be? No interior sound for the airbrakes in the A-10C? I only hear what I think is the 'SpeedBrakeWindIn' file.
I have made copies of the 'AirBrake' and 'AirBrakeEnd' wav files and renamed them 'AirBrakeIn' and 'AirBrakeEnd'. I copied sdef files 'FlapsIn' en 'FlapsEndIn' and changed the names to 'AirBrakeIn.sdef' and 'AirbrakeEndIn.sdef'
Listening to the difference between the Flaps and FlapsIn, and the FlapsEnd and FlapsEndIn wav files, I opened the two new AirBrake files in audicity and created more muffled copies of them.
The two new wav and corresponding sdef files were then copied to their respective folders (like all the Flaps files), started up DCS, but the sounds won't run. Still Only 'SpeekBrakeWindIn' I believe.
So, is there some line of code I need to add to another lua file, or is it impossible to add this,
trigger the 'AirBrakeIn' sound on deploying the airbrake?
