Audio formats have developed over time. Starting with narrow mono bandwidth, moving to various versions of two-channel stereo and finally full-band multi-channel immersive audio. Sound is reproduced in many ways, from personal headphones to multi-channel systems in cinemas or other large venues. Immersive audio can be described as a group of recording and playback formats that involve more than a basic two-channel stereo.
Immersive audio encompasses all surround formats.
