Two-Channel Systems TRIZ Cases
- Stereo Audio Bass Processing for Wide Soundstage Without Noise
Band-split bass processing with dynamic range control widens stereo sound while preserving soundstage fidelity and limiting noise.
- Audio Diffusor Filtering for Externalized Headphone Spatial Sound
A diffusion filter, delay, and distance-gain mixing recreate air and room cues so headphone audio sounds externalized and more spatially realistic.
- 3D Audio Spatial Resolution Control to Prevent Output Delay
Spatial resolution and response length are adjusted by head and sound-source position to cut 3D audio processing delay while preserving voice quality.
- Neural HRTF Retrieval for Personalized Spatial Audio
Retrieved HRTFs and a neural field model personalize spatial audio while reducing listener-specific HRTF measurement time.
- Interaural Time Delay Shifting to Reduce Binaural Comb Filtering
Redistributing ITD delays toward the contralateral ear reduces ipsilateral comb filtering while preserving binaural timing cues.
- Stereo Audio Image Enhancement Using Acoustic Image Metrics
Automatic stereo mastering compares channel balance and width metrics to reference targets, improving stereo imaging with less manual effort.
- Spatial Audio Adjustment Using Head Rotation Prediction
Machine-learning head rotation prediction lets spatial audio adjust amplitude and phase ahead of motion, cutting delay and improving 3D sound coherence.
- HRTF Frequency Region Tuning for Vertical Sound Localization
Targeted amplitude tuning of contralateral HRTF frequency regions shifts perceived sound elevation while limiting distortion and processing load.
- Head-Related Filter Error Correction for Spatial Audio Continuity
Model-based correction cleans misaligned HR filters and non-HR reflections to improve spatial continuity and binaural XR immersion.
