Introduction
Binaural audio simulates the natural hearing experience by delivering separate sound signals to each ear, creating the illusion of 3D space over headphones.
Technical Overview
- HRTF-based modeling: Filters sounds according to the listener’s anatomy
- Spatial cues: Interaural time difference (ITD) and interaural level difference (ILD)
- Head tracking integration: Dynamic updates based on head orientation
Applications
- Audio-first games for navigation and spatial awareness
- VR/AR simulations
- Training and rehabilitation applications
Design Considerations
- Ensure consistent cue perception across listeners
- Avoid auditory fatigue by balancing sound intensity and frequency range
- Integrate environmental reflections for realism
