Claim 5:
6. A computer program product residing on a non-transitory computer readable medium having a plurality of instructions stored thereon which, when executed by a processor, cause the processor to perform operations comprising:
generating a plurality of acoustic relative transfer functions for a plurality of audio acquisition devices of an audio recording system deployed in an acoustic environment;
encoding 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
extracting information from at least 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.
