Objective and Subjective Evaluation of Head - RelatedTransfer Function Filter

In this paper, the problem of modeling head-related transfer functions (HRTFs) is addressed. Traditionally, HRTFs are approximated in real-time applications using minimum-phase reconstruction and various digital lter design techniques, yielding FIR or IIR structures. In this work, binaural auditory modeling has been applied to HRTF analysis and lter design methods have been compared from the auditory perception point of view. This paper presents applicable perceptually valid lter design techniques and discusses listening test results for localization and timbre degradation.
