Abstract
Current audio/video head-mounted rendering systems for virtual and augmented reality rely on a binaural approach combined with Ambisonics technology. These head-tracking systems employ generic HRTFs commonly measured with a dummy head in anechoic room. In this paper, we describe a new solution that has been designed to play 360 video files with spatial audio, developed for desktop and portable platforms and built from existing open source software. The HRTF sets can be loaded from a standard audio file chosen in an existing database or from an ad-hoc measurement. The capability to switch multiple HRTF sets while playing files has been added.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
