Pseudo-Stereo Systems TRIZ Cases

Distinct low and high frequency filter estimators apply HRTF cues to create elevated sound perception while minimizing inter-zone leakage.

Dynamic HRTF adjustment maintains geographic sound fixation despite user movement, resolving the trade-off between immersive adaptability and spatial stability.

Mid-side processing creates a broad sound field in compact environments, eliminating the need for separate woofers while enhancing bass reproduction.

Decomposes head-related impulse responses into sparse filters to enable real-time spatial audio synthesis, reducing computational costs.

A signal processing device calculates audio signals for loudspeakers based on virtual sound source distance.

A variable matrix maps input audio channels to output channels based on signal correlation and levels.
