Abstract

A method and system for generating an auditory scene that comprises: receiving eigenbeam outputs, the eigenbeam outputs having been generated by decomposing a plurality of audio signals, each audio signal having been generated by a different microphone of a microphone array, wherein each eigenbeam output corresponds to a different eigenbeam for the microphone array; generating the auditory scene based on the eigenbeam outputs and their corresponding eigenbeams, wherein generating the auditory scene comprises applying a weighting value to each eigenbeam output to form a steered eigenbeam output; and combining the weighted eigenbeams to generate the auditory scene, wherein generating the auditory scene further comprises applying a regularized equalizer filter to each eigenbeam output or steered eigenbeam output, the regularized equalizer filter(s) being configured to compensate for acoustic deficiencies of the microphone array and having a regularized equalization function.
