A bed is a channel-based premix or stem that includes multichannel panning, and does not need dedicated
panning via Dolby Atmos metadata. Use a bed for stereo or surround panning.
A bed can be thought of as a traditional channel-based stem with the rules and expectations of stem
configurations (such as 2.0, 5.1, and 7.1). These are fixed locations in space that are tightly constrained to
traditional speaker environments, including theatrical environments where a speaker array might be used.
In Dolby Atmos, the largest bed configuration that exists is 7.1.2. This configuration allows for Low-
Frequency Effects (LFE), with left and right side walls, and an additional overhead stereo pair. Dolby Atmos
supports the use of multiple beds.
