Abstract

In binaural synthesis, signals are convolved with head-related transfer functions HRTFs. In dynamic systems, the update is often done by cross-fading between signals that have been filtered in parallel with two HRTFs. An alternative to cross-fading that is attractive in terms of computing power is direct switching between HRTFs that are close enough in space to provide an adequate auralization of moving sound. However, direct switching between HRTFs does not only move the sound but may also generate artifacts such as audible clicks. HRTF switching involves switching of spectral characteristics and timing characteristics (ITD) and the audibility of these were studied separately. The first results, data on minimum audible time switch, MATS, are presented.
