Pseudo-Stereo Systems TRIZ Cases
- Bass Extraction and Routing for 3D Audio Bass Build-Up
Low-pass bass extraction before object rendering routes low frequencies to capable speakers, reducing bass build-up in 3D layouts.
- Bass Extraction Routing for Multi-Speaker Build-Up Control
Low-pass bass extraction and targeted speaker routing curb bass build-up during array processing in multi-speaker audio playback.
- Virtual Surround Sound Filtering for Headphone Sound Externalization
Combined room and head-related impulse response filtering moves headphone surround sound from in-head playback to realistic external locations.
- Bass Extraction and Routing to Prevent 3D Audio Bass Build-Up
Low-pass bass extraction and speaker routing isolate low frequencies before rendering, reducing bass build-up in complex 3D audio layouts.
- Virtual Loudspeaker Placement for Spatial Audio Extent Rendering
Adaptive middle virtual loudspeaker placement and attenuation preserve even spatial audio extent rendering with low complexity in XR.
- Virtual Top-Channel Surround Mixing for Off-Sweet-Spot 3D Audio
Crosstalk-cancelled top channels are mixed into surround speakers to create virtual height audio with better spatial accuracy away from the sweet spot.
- Object-Based Audio Rendering for Flexible Listening Position Control
Adjusts object positions, gain, frequency response, and spatial acoustics to preserve accurate sound images across different listening positions.
- Object Extraction Feedback for Artifact-Free Channel Audio Conversion
Feedback scoring compares rendered and original channel audio to correct extraction artifacts and improve object-based conversion quality.
