Sažetak
With the recent leaps in the development of virtual reality (VR) systems, it was necessary to design audio systems as well, as they are a significant aspect of the complete VR experience. Although audio systems have often been neglected within VR systems, technology giants like Samsung and Apple have recently begun developing audio systems that allow users to experience spatial audio instead of standardized stereo audio. To properly reproduce a spatial audio signal, i.e. simulate a different audio environment, it is necessary to track the position of the human head. This can be done in a variety of ways, for example, using face detection to calculate head tilt. Currently, the most used method is the use of head-tracking devices that use inertial measurement unit (IMU) sensors to calculate the position of the user's head. In this paper, the importance of audio systems for spatial audio signal reproduction with head-tracking will be discussed, and methods for synthesizing audio signals using information from IMU sensors will be presented.
