Abstract (en)
[origin: WO2022008092A1] Determining Par-Hilbert invariants is a reliable means in the area of real-time transmission of spatial audio signals. So-called CC-HRTFs allow an inverse stable model of the spatial perception both on headphones and on loudspeakers while allowing distinct localization in a three-dimensional space.
