AB  - Binaural audio is a relevant rendering technique for mass diffusion in immersive experiences. By adding a head tracking system, dynamic binaural rendering can improve the overall quality in comparison with static rendering. However, introduced latency between the head movement and the audio rendering is detrimental to the audio experience. Previous studies estimated the latency detection threshold for binaural listening, but the influence of head movements remains unclear. In this paper, two listening tests on latency detection threshold are presented. Several excerpts were used: pink noise, male speech, a pair of congas, and coffee shop ambiance. The first experiment investigated the influence of head rotation speed on the latency detection threshold. The second experiment focused on the impact of head-related transfer functions. An absolute judgment protocol was used in both tests. Results showed that latency was globally easier to detect with faster movement for expert subjects. No global differences between nonindividual and individual head-related transfer functions were observed. In both experiments, pink noise led to a significantly lower latency detection threshold. Large intersubject differences were also observed.
