3.4 SOUND SETUP
New Engine Sounds: This enables a new method of playing engine sounds. The biggest
difference between this method and the old, is that there is no longer an "After Burner" sound;
instead, as power increases, you get an increasing roar.
Enable Doppler Effect: This enables a new method of playing engine sounds. The biggest
difference between this method and the old, is that the doppler effect changes the pitch of sounds
depending on the movements of the listener and the object creating the sound.
Enable Distance Effect: This attempts to simulate distance between the listener and the object
emitting sound. Sounds will have to travel to the listener to be heard. This is characterized by a
“pause” between when an event, such as an explosion occurs, and when it is actually heard. For
fast moving objects such as aircraft, sound will appear to come from a distance behind,
depending on the speed of the object, and the distance between the object and listener.
Internal Sounds Outside Cockpit: This enables or disables playing Betty sounds while in
external views.
External Sound Slider: While in-cockpit, and with the canopy closed, this slider will lower or
boost the volume of external sounds. This adjustment is added to the aircrafts default value for
