Claim 10:
11. A computing system comprising:
a memory; and
a processor configured to generate a plurality of acoustic relative transfer functions for a plurality of audio acquisition devices of an audio recording system deployed in an acoustic environment, wherein the processor is further configured to encode the plurality of acoustic relative transfer functions into a first embedding of acoustic relative transfer functions and at least a second embedding of acoustic relative transfer functions, wherein encoding the first embedding of acoustic relative transfer functions includes encoding the first embedding with a first degree of precision and wherein encoding the at least a second embedding of acoustic relative transfer functions includes encoding the at least a second embedding with at least a second degree of precision, and wherein the processor is further configured to extract information from the first embedding of acoustic relative transfer functions via a machine learning model trained to minimize a direction-of-arrival (DOA) estimation error between a reconstructed signal after encoding and an uncompressed signal when extracting the information from at least the first embedding of acoustic relative transfer functions.
