In the current effort to improve sound for virtual auditory environments, realism and audio quality in head-tracked binaural rendering is again becoming important. While rendering based on static dummy-head measurements achieve high audio quality and externalization, the realism lacks interactivity with changes of the head orientation. Motion-tracked binaural (MTB) has been presented as a head-tracked rendering algorithm for recordings made with circular arrays on rigid spheres. In this contribution, we investigate the algorithm proposed for MTB rendering and adopt it for variable-orientation rendering using binaural room impulse responses (BRIR) measured for multiple, discrete orientations of an artificial-head. The experiment in particular investigates the perceptual implications of the angular resolution of the multi-orientation BRIR sets and the time/frequency-resolution of the algorithm.
