Pseudo-Stereo Systems TRIZ Cases
- Digital Processor for Individual 3D Sound in Cars
A digital processor extracts ambient portions from multi-channel signals to generate spatial effect signals for individual three-dimensional sound reproduction.
- Audio Spatial Effect Enhancement via Time-Varying Signal Modulation
A stereo audio enhancement architecture modulates summation and ambience signals with time-dependent functions to generate dynamic spatial effects.
- Multichannel Audio Coding Phase Compensation
N:1:N spatial audio coding applies phase compensation and angle rotation to reduce coupling cancellation artifacts at low bitrates.
- Early Reflection Generator for Natural 5.1 Audio Down-mixing
An early reflection generator synthesizes spatial audio cues for headphone playback.
