摘要

Spatial audio implementations with binaural playback benefit from personalized HRTF sets. Thus access to an efficient procedure for capturing individual Head Related Transfer Functions (HRTF) is beneficial for media production as well as for research and development in the field. In the newly established Immersive Audio Lab at Hamburg University of Applied Sciences we implemented a fast HRTF measurement procedure in a 33-channel loudspeaker dome, utilizing the Multiple Exponential Sweep Method (MESM) introduced by Majdak, Balazs and Laback [1]. One measurement of about 4 minutes results in a set of 289 discrete HRIRs, covering 360° in the horizontal plane and roughly -15°...90° elevation.
