Objective and Subjective Evaluation of Head-Related Transfer Function Filter Design

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 filter design techniques, yielding FIR or IIR structures. In this work, binaural auditory modeling has been applied to HRTF analysis, and filter design methods have been compared from the auditory perception point of view. Applicable perceptually valid filter design techniques are presented, and listening test results for localization and timbre degradation are discussed.
