Object-based audio renders sound per-loudspeaker via metadata at playback time
Evidence
Some audio formats meant primarily for cinema also allow the use of different multi-channel systems to reproduce the audio content. The audio is sent with some metadata, which then defines how the sound is rendered to the loudspeakers. The corresponding methods are called object-based audio techniques. Such systems, like those covered by Robinson et al. (2012) and Lemieux et al. (2013), are called loudspeaker-set-up agnostics. The first movies with sound tracks in such formats were released in 2012. — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1813

- DEFINE: Clears up what ‘object-based audio’ and ‘loudspeaker-set-up agnostic’ mean: sound is rendered at playback from metadata rather than pre-mixed to channels.
