| Opis: | Spatial audio is central to immersion and situational awareness in virtual reality (VR), but the performance differences between diferent audio engines have not been sufficiently explored. This study compares Unity’s integrated spatial audio system and the FMOD engine in a controlled VR sound localisation task. Thirty volunteers completed three levels of 16 trials each while wearing a head-mounted display (Oculus Quest). They were randomly assigned to one of the two systems and asked to identify the direction of an active loudspeaker among several virtual sources. We measured localisation accuracy, reaction time, spatial distance error and cumulative head rotation; learning effects were assessed by comparing the first and third stages. Participants using FMOD achieved slightly higher accuracy (93% vs 87% overall) and turned their heads less, suggesting that FMOD made it easier for users to localise sounds in space, while Unity users showed greater variability and a slightly greater learning gain. About two-thirds of participants improved their accuracy over time, but there were significant individual differences. These results suggest that both engines perform similarly well on basic localisation tasks, although FMOD has slight advantages in spatial accuracy. The work highlights the importance of evaluating spatial audio engines in user-centred studies and emphasises the need to consider personal factors and task complexity in future research. |
