Air Brake Sound Controller

Manages sound effects for pneumatic air brake operation — the characteristic hiss of air release when brakes are applied and released on heavy trucks.

Linear Movement Sound Controller

Plays sound effects synchronized with linear actuator or hydraulic cylinder movement. Maps actuator position/speed to sound playback for realistic mechanical audio feedback.
