Choose your engine
Pick the engine sound that fits your drive.
Motion becomes sound
The engine follows
the road.
Your phone supplies movement. REVTHRUM builds the virtual powertrain around it, in real time.
Invisible technology
One tap.
The rest is automatic.
REVTHRUM translates phone speed and acceleration into a responsive virtual powertrain. No vehicle installation. No diagnostic-port adapter.
Connect your audio
Route phone audio through the vehicle's Bluetooth system.
Start while parked
REVTHRUM handles acceleration, drivetrain response, cruising, and slowdown.
Built, not sampled
Combustion events—not a looping recording.
Each engine is generated in real time from bank-specific firing pulses, exhaust resonance, intake load, and its own virtual drivetrain behavior. No manufacturer recordings or vehicle trademarks.
- Five distinct sound profiles
- Load-sensitive intake and exhaust
- Geared and continuous-drive response
- On-device speed processing
Designed for focus
Set it before you move.
REVTHRUM is a foreground web app. Connect Bluetooth, choose a sound, and set volume while parked. It estimates virtual engine response from phone speed; it does not read your vehicle's real RPM, throttle, or mechanical condition.
