Binaural Rendering
Demo - Binarual rendering
For the demo, put on the headphones and move your head according to the illustration. Also, imagine that there is a speaker in front of you.
Recently, with the emergence of Apple's spatial audio technology and Meta's AR/VR devices,
technologies that render virtual audio as if it were actually present in the real world are gaining traction.
Virtual audio for AR/VR devices is played through headphones. However, it is challenging to provide a sense of reality and spatiality, through audio played via headphones.
For listeners to perceive these senses, it is essential to consider direct sound, reflections, and multimodal elements such as visual information, and head rotation when rendering audio. Audio rendering that takes into account these factors can be achieved through the convolution of Binaural Room Impulse Response (BRIR) with the anechoic audio source.
While using measured BRIR for audio rendering is ideal, it is not feasible to measure them in every situation as BRIR varies depending on factors such as room size, listener's position, and speaker location. Therefore, we are researching how to efficiently design BRIR for the perception of reality and spatial characteristics.
