Vehicle Sound Effects
Available from ModelExtras v2.0+
ModelExtras features an immersive, dynamic 3D Vehicle Sound System that plays realistic spatial audio cues during vehicle interactions, engine states, emergency operations, and heavy machinery operations.
Built-in effects use files in ModelExtras/audio/. The regular effect loader searches .mp3, .wav, and .ogg for the expected base filename; siren sounds use the path configured on each siren state.
Place replacement audio files inside ModelExtras/audio/ using these base names:
| Sound File | Trigger Event | Affected Vehicles |
|---|---|---|
engine_start.wav |
Starting the vehicle engine | Automobiles, Trucks, Vans |
bike_engine_start.wav |
Starting a bike or motorcycle engine | Motorcycles, Quadbikes |
indicator_on.wav |
Turn signal or hazard light engaged | Player vehicle |
indicator_off.wav |
Turn signal or hazard light disengaged | Player vehicle |
switch_toggle.wav |
Toggling fog lights, spotlights, or high beams (when headlights active) | Player vehicle |
airbreak.wav |
Releasing air brakes after deceleration | Heavy vehicles (Trucks, Buses, Monster Trucks) |
reverse.wav |
Reversing / Backup warning beeper | Heavy vehicles in reverse gear |
backfire.wav |
High-RPM pop-and-bang backfire explosions & gear shifts | Sports cars & high-performance models |
door_chime.mp3 |
Warning chime while a qualifying vehicle door is open | Selected vehicles by default |
brake_pad.mp3 |
Brake-pad squeak while braking at low speed | Selected vehicles when enabled |
| Custom siren audio paths | Per-state sound value in siren JSONC (switched via CTRL + 1..9) |
Siren states that specify matching audio paths |
You can individually toggle, adjust volume, or configure which vehicle models receive heavy vehicle sound effects:

The loader searches .mp3, .wav, then .ogg for the built-in door_chime and brake_pad names.
Siren audio is configured per state using its sound field, for example "sound": "audio/siren3.wav"; the path is relative to ModelExtras/. Ctrl + 1..9 selects a configured siren tone/state sound. There are no built-in siren_tone1.wav ... siren_tone9.wav files. Siren paths are loaded as written.
The audio system uses positional playback. Configured siren streams can continue at the vehicle position after the player exits.
