Renderers use metadata to adapt recordings to any loudspeaker configuration.

Evidence

Metadata is included in recordings describing loudspeaker and channel allocations and positions so that a rendering algorithm can adapt the recording to be compatible with the loudspeaker configuration in the playback system. It is something that technically inclined enthusiasts might be interested in, but in the end, customers are rarely informed about what they are listening to, and what compromises have been made in the delivery process. — Toole, Floyd E, Sound reproduction- the acoustics and…, 865
