Objective and subjective evaluation of head-related transfer function filter design

The problem of modeling head-related transfer functions (HRTFs) is addresse d. Traditionally HRTFs are approximated in real-time applications using min imum-phase reconstruction and various digital filter design techniques, yie lding FIR or IIR structures. In this work, binaural auditory modeling has b een applied to HRTF analysis, and filter design methods have been compared from the auditory perception point of view. Applicable perceptually valid f ilter design techniques are presented, and listening test results for local ization and timbre degradation are discussed.
