Binaural Audio and Head-Related Transfer Functions (HRTFs)
Binaural audio replicates natural 3D hearing by using at least two audio channels, one for each ear
Head-Related Transfer Functions (HRTFs) are spectral fingerprints that capture how sound sources are modified by the head and ears
Binaural audio is synthesized through HRTF over 2-channel systems, enabling the perception of virtual 3D sound sources in any direction around the listener
This process delivers accurate sound localization and enhances depth perception between close and distant sounds
Cross-talk Cancellation (CTC)
Conventional stereo systems converge and flatten spatial cues
The perception of spatial audio over headphones is readily achieved due to the separation of left and right channels
CTC is processing that enables binaural reproduction through loudspeakers instead of headphones
Like a 'virtual headphone', CTC uses interference cancelling filters to ensure each ear receives only its intended audio signal
CTC signal separation unlocks HRTF encoding and the perception of spatial cues
Compared with headphone reproduction of binaural audio, CTC delivers greater externalization
Speaker Beamforming
Processing technique that manipulates the phase and amplitude of audio signals across multiple speakers
Controls the size, shape, and direction of acoustic waves to create focused sound beams directed at the listener
Enhances the effectiveness of cross-talk cancellation by improving channel separation and reducing interfering sources
Multi Channel Arrays
Uses three or more loudspeakers for improved 3D sound reproduction through speaker beamforming
Enhances the effectiveness of cross-talk cancellation by improving channel separation and reducing interfering sources
Increases loudness while reducing room reflections, improving overall sound quality
Scalable from slim notebooks, to soundbars, to multi-speaker display designs
Position-Adaptive 3D Sound
Overcomes the sweet-spot limitation of conventional cross-talk cancellation systems
Uses Machine Learning powered listener-position sensing to track the alignment of the listener's ears to the audio device
Dynamically adjusts audio processing to maintain optimal 3D sound as the listener moves
Provides a consistent, high-quality 3D audio experience regardless of listener position
