Claim 8:
9. A system for processing audio information to update a frame of reference for a spatial audio signal, the system comprising:
a spatial audio signal processor circuit configured to:
receive a first spatial audio signal from an audio capture source, the audio capture source having a first frame of reference relative to an environment, and the first spatial audio signal including multiple signal components representing audio information from different depths or directions relative to a location of the audio capture source in the environment;
receive information about a second frame of reference relative to the same environment, the second frame of reference corresponding to a second capture source;
determine a difference between the first and second frames of reference;
decompose the first spatial audio signal into respective audio signal components, each audio signal component having a corresponding position in the environment;
select, based on the determined difference between the first and second frames of reference, respective filters for processing the audio signal components of the first spatial audio signal;
apply the selected filters to the respective audio signal components of the first spatial audio signal to generate respective spatially transformed components; and
using the spatially transformed components, generate a second spatial audio signal referenced to the second frame of reference.
