""Can you maybe give some hint?"" The most commonly used model for HRTF implementation is the one refered to as "minimum phase filter and pure delay".It is composed of: -a minimum-phase filter, which accounts for the magnitude spectrum of HRTF -and a pure delay , which represents the temporal infor
