Binaural Cue Adaptation (BCA)

Background: Binaural 3D Audio Signals

• Recorded using two microphones in or near the ears
• Stored and transmitted like stereo signals
• Playback on headphones creates spatial sensation
• Spatial immersion essential for VR/AR applications

Dynamic Binaural Cue Adaptation (BCA)

• Adapts binaural signals to listener's head movements using head orientation sensor
• Makes binaural recordings immersive and suitable for Virtual / Augmented Reality applications

Implemented entirely in Hearing Device

• Works with any existing playback devices over existing interfaces (e.g., headphone jack, Bluetooth) without any modifications, drivers or special apps
• Compatible with pre-existing binaural / dummy head recordings and synthetic binaural signals
• Content distribution using established storage and transmission media, codecs, platforms, etc.
