Changes the sounds of autocannons, small rocket motors, small modular engines, 3x1 modular engines, turret rings , hardpoints and pumps.
Heavy AC sounds more like a 57mm
Light AC sounds like a BMP firing
Small rocket motors when starting sound like a Tow launcher
1x1 modular engine sounds like a normal small diesel engine
3x1 modular engines sound like radials
turret rings and pumps make more realistic sounds that don't deafen you
a sad secondary effect is that jet engines now sound like tow launchers when they start combustion
