A psychoacoustical audio technique creating a spatial perception of sound absence or void between stereo channels.

Patentradars sammanfattning

The invention relates to psychoacoustical phenomena in audio processing, specifically addressing the perception of a 'psychoacoustical hole'—an auditory effect where listeners perceive a spatial gap or absence of sound in the stereo field. The document presents technical configurations for generating or manipulating this perceptual effect through speaker placement (SP-L, SP-R) and listener positioning, as illustrated in the accompanying figure. This technique has applications in spatial audio rendering, immersive sound design, and psychoacoustics research.
