1. A device comprising:
a memory configured to store audio data representative of a soundfield captured at a plurality of capture locations, metadata that enables the audio data to be rendered to support N degrees of freedom, and adaptation metadata that enables the audio data to be rendered to support M degrees of freedom, wherein N is a first integer number and M is a second integer number that is different than the first integer number; and
one or more processors coupled to the memory, and configured to:
determine a user location by receiving, from a user, an input indicative of one of a plurality of locations or indicative of a position on a trajectory;
adapt, based on the adaptation metadata, the audio data to provide the M degrees of freedom; and
generate speaker feeds based on the adapted audio data.
