3D Sound

3D sound, or spatial audio, is a technique used to simulate how humans perceive sound in three dimensions—left/right (azimuth), up/down (elevation), and near/far (depth). This can be achieved through binaural recordings using dummy heads with microphones in their ears, or digitally through head-related transfer functions (HRTFs), ambisonics, and multichannel systems like Dolby Atmos. 3D sound aims to replicate the way sound waves interact with the listener’s head and ears, providing an immersive and realistic sound field.
