Stereophonic Systems TRIZ Cases
- Audio Processing via Environmental Sensor Profiling
Audio processing system profiles environmental parameters to enhance signal quality.
- Parametric Binaural Headphone Rendering via Sum and Cross Filters
Sum and cross filters process stereo signals to simulate desired sound systems without introducing coloration or resonance artifacts.
- VR Audio Doppler Simulation via Physics-Based Frequency Shifts
Physics simulation determines frequency shifts from motion data, enabling real-time Doppler effect rendering without excessive computational complexity.
- Upward-Firing Speaker Array for Immersive Audio in Portable Devices
Upward-firing speaker array projects sound vertically to create near-field audio fields, enabling immersive height cues without increasing device volume.
- Loudspeaker Self-Calibration Using Internal Signal Generation
A loudspeaker system generates its own test signals to measure frequency response and adjust equalization filters in real time.
- Acoustic Head Model Using Ray-Tracing and Near-Field Compensation
A high-frequency head model uses ray-tracing and half-plane sections to predict interaural time differences.
