Spatial Audio & 3D Radar

Limited in browser

Experience 3D binaural spatial positioning rendered directly in stereo headphones using Web Audio Head-Related Transfer Function (HRTF).

Safe listening:Binaural HRTF positioning intentionally feeds both ears with different timing and level cues. Use the channel test—not this spatial test—when you need complete left/right isolation.

What to listen for

  • •Binaural vs Channel Isolation: Some signal in both ears is expected; direction comes from the difference between the two ear signals.
  • •Front vs Rear Localization: Sounds positioned behind you feature subtle high-frequency attenuation simulating natural ear pinna filtering.
  • •360° Orbit: The audio beacon should move smoothly in a full circular orbit around your head.
  • •Browser Environment: Uses Web Audio HRTF positioning. Native mobile apps can additionally access hardware motion head-tracking sensors.

Technical context

Binaural Rendering: Web Audio API models sound direction via HRTF algorithms.

Operating-system spatial audio (e.g. Apple Spatial Audio, Dolby Atmos) and hardware head-tracking sensors operate at the OS level and are not accessible in standard browsers.
