Claim 0:
1. A method for updating a frame of reference for a spatial audio signal, the method comprising:
receiving 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;
receiving information about a second frame of reference relative to the same environment, the second frame of reference corresponding to an image capture sensor;
determining a difference between the first and second frames of reference;
decomposing the first spatial audio signal into respective audio signal components, each audio signal component having a corresponding position in the environment;
selecting, 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;
applying 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, generating a second spatial audio signal referenced to the second frame of reference.
