Two-Channel Systems TRIZ Cases
- Stereo Image Widening via Acoustic Dipole Signal Inversion
Acoustic dipole signal inversion mitigates crosstalk between loudspeakers, expanding the listener sweet spot without complex head-related transfer functions.
- Smartphone Binaural Audio Personalization via BRIR Measurement
A mobile device measures binaural room impulse responses using its built-in loudspeaker and microphone to personalize audio playback.
- BRIR Filter Decomposition for Binaural Spatialization
Decomposes BRIR filters into delay and spectral modules, reducing computational costs while preserving externalization.
- Stereo Image Widening via Sum-Difference HRTF Processing
Sum-difference conversion isolates the difference channel for HRTF processing, widening the stereo image beyond physical speaker constraints.
- Audio Device Crosstalk Cancellation Using Signal Segmentation
Segmenting audio into in-phase and anti-phase components allows selective crosstalk cancellation that preserves center-localized sound quality.
- Audio Signal Processing Apparatus for 3D Binaural Synthesis
Audio signal processing apparatus reduces memory requirements by extending two-dimensional transfer functions to three dimensions via interpolation.
