Qooder Quadro4 2015 quadricycle scooter motorcycle

The Qooder Quadro4 is a revolutionary four-wheeled tilting quadricycle scooter that bridges the gap between a modern maxi-scooter and a light compact vehicle. Powered by a liquid-cooled 346cc four-stroke engine featuring dual rear-wheel drive and hydraulic tilting suspension, its acoustic signature is unique, combining a deep single-cylinder exhaust note with smooth mechanical engine hums, distinct hydraulic tilting suspension creaks and solid four-wheeled road tracking. This specialized sound library captures the full operational profile of an innovative all-weather commuter, providing an essential acoustic toolkit for modern urban mobility, futuristic vehicle sound design, film post-production mixing and game audio physics.

Whether you need to build continuous steady-RPM loops for vehicle simulation, record technical cornering maneuvers with dynamic weight transfer or source crisp multi-take physical foley, the Qooder Quadro4 library offers a versatile, high-resolution toolkit.

Dual-Perspective Synchronized Tracking: Features phase-aligned multi-channel recordings capturing separate focal points from the engine perspective (mechanical intake, CVT drive whines and motor block dynamics) and the exhaust perspective (throaty four-stroke tailpipe pulses, exhaust pressure and deep low-end idle rumble).

Static RPM Holds & Technical Driving Dynamics: Includes isolated steady-state RPM step recordings (3000 and 4000 RPM) across both perspectives for seamless game engine looping curves, paired with technical maneuvers like cornering, U-turns, coasting in neutral, active speed fluctuations and multi-velocity external pass-bys.

Pristine High-Resolution Capture: Recorded at 192 kHz / 32-bit float using the high-headroom Sound Devices MixPre-6 II recorder. Captured with a professional mic array consisting of the RØDE NTG1 shotgun, Line Audio Omni1 omnidirectional and low-noise FEL Clippy XLR EM272 microphones for pristine mechanical transients and ultra-low noise floors.

Comprehensive Mechanical Foley Set: Archives 78 total WAV files covering physical interactions, including multi-take mechanical handbrake engagements, passenger footrest deployments, storage compartment latches, ignition key operations, light switches and horn blasts.
