Simultaneous HRTF Measurement of Multiple Source Configurations Utilizing Semi-Permanent Structural Mounts

Document Thumbnail

A compact HRTF measurement rig has been designed and erected within the anechoic chamber at AudioLab, University of York. Utilizing 24 discrete elevations the efficient simultaneous HRTF measurement of 11 popular source configurations, ideally suited for the binaural rendering of Ambisonics, is undertaken. An overlapped exponential swept sine technique is used to make optimal use of a subject’s time. This report details the practical requirements, technical workflow and processing involved in the HRTF measurements, for inclusion to the SADIE database. The necessary modelling of low frequency cues is discussed.
