Stereophonic Systems TRIZ Cases
- Personalised HRTF Synthesis with Precomputed Timbre Components
The case removes spectral notches, extracts subject-specific HRTF timbre, and combines stored components for efficient runtime synthesis.
- Time-Varying Recursive Filters for Low-Cost Virtual Acoustic Rendering
This case models sound reception and emission with mutable recursive filters, reducing computation and memory demands for interactive audio.
- Sound Processing for Indirect Sound Localization via Object-Channel Selection
This case selects object- or channel-based processing for indirect sounds, balancing reverberation realism with computational load.
- Spatial Audio Signal Processing for Device Movement Tracking
Distance and angle data update audio remapping so wearable sound sources stay consistent as a mobile device moves.
- Audio Render Analyzer for Real-Time Inter-Channel Feature Display
A graphical audio render analyzer measures correlation and spectral flux to guide adaptive processing across speaker configurations.
- Volumetric 3D Audio Rendering for Dynamic Occlusion and Adaptive Detail
Geometric sound volumes and distance-based audio detail streamline dynamic 3D rendering while preserving realistic occlusion.
- Audio Element Rendering with Adaptive Loudspeakers Against Comb Filtering
This case adapts virtual loudspeaker count to audio size and listener distance, reducing comb filtering and psychoacoustic holes.
- Dynamic Crosstalk Cancellation Filters Using Dimensional Maps
Precomputed transfer functions in a dimensional map reduce filter storage and accelerate crosstalk cancellation for moving users.
- Audio Mixing with Combined Rotation and Translation for Low Latency
Precomputed rotation matrices and translation vectors help client devices correct avatar audio positioning without added bandwidth.
- Spatialized Audio IIR Filtering via Modal Impulse Interpolation
A neural network interpolates impulse-response modes to drive compact IIR filters, reducing memory and computation for directional audio.
- Head-Size Adapted Binaural Audio for Near-Field Vehicle Speakers
Vehicle sensors detect ear position or head size, enabling tailored crosstalk cancellation for accurate spatialized audio.
