Spatial Audio Test System

CRYSOUND provides a spatial audio testing system based on a three-axis motorized rotary platform, enabling fast and stable evaluation of spatial audio functionality.

Overview

With the continuous growth in consumer demand for immersive experiences, spatial audio has become a key differentiating feature for a wide range of audio devices. However, achieving efficient, stable, and objective measurement of spatial audio performance during mass production remains a common challenge across the industry.

CRYSOUND provides a spatial audio testing system based on a three-axis motorized rotary platform, enabling fast and stable evaluation of spatial audio functionality. Inside the shielding enclosure, headphones are connected via the CRY576 Bluetooth adapter for IMU data acquisition and analysis.
This system introduces objective measurement metrics for spatial audio performance, effectively ensuring product-level consistency and reliability.
