Claim 15:
16. A method for changing a frame of reference for a first spatial audio signal, the first spatial audio signal including multiple signal components representing audio information from different depths or directions relative to an audio capture location associated with an audio capture source device, the method comprising:
receiving components of the first spatial audio signal from the audio capture source device, the audio capture source device having a first reference origin and a first reference orientation relative to an environment;
receiving information about a second frame of reference relative to the same environment, the second frame of reference corresponding to an image capture source, and the image capture source having a second reference origin and a second reference orientation relative to the same environment;
determining a difference between the first and second frames of reference, including at least a translation difference between the first and second reference origins and a rotation difference between the first and second reference orientations; and
using the determined difference between the first and second frames of reference, determining respective filters to use to generate components of a second spatial audio signal, and generating the second spatial audio signal with the components of the second spatial audio signal, wherein the generated components of the second spatial audio signal are-based on corresponding components of the first spatial audio signal and the second spatial audio signal is referenced to the second frame of reference.
