Abstract

The purpose of this paper is to describe a novel method for auralizing measured room impulse responses over headphones using impulse responses recorded from a 16-channel spherical microphone array decoded to eight virtual loudspeakers mixed-down binaurally using nonindividualized HRTFs. The novelty of this method lies not in the ambisonic binaural-mixdown process, but rather, the use of head pose estimation code from the Kinect API sent to a Max/MSP patch using Open Sound Control messages. This provides a fast, reliable alternative to auralizations over headphones that allow for head movements without the need for head-related transfer function interpolation by performing a rotation on the spherical harmonic that corresponds to the listener's head rotation.
