Spatial audio

Definition

Spatial audio refers to an immersive sound experience that simulates a three-dimensional audio environment, allowing listeners to perceive sound from various directions and distances. This technology enhances the realism of audio by placing sounds in a three-dimensional space, making it particularly effective for applications like virtual and augmented reality, where creating an immersive experience is crucial.
