Bayesian optimization for simultaneous deconvolution of room impulse responses

Abstract

One embodiment provides a method comprising optimizing one or more stimuli parameters by applying machine learning to training data. The method further comprises determining, based on the one or more optimized stimuli parameters, stimuli for simultaneously exciting a plurality of speakers within a spatial area. The stimuli has a shortest possible duration that is accurate for simultaneous deconvolution of a plurality of impulse responses of the plurality of speakers. The method further comprises simultaneously exciting the plurality of speakers by providing the stimuli to the plurality of speakers at the same time for reproduction. The method further comprises simultaneously deconvolving the plurality of impulse responses based on the stimuli and one or more measurements of sound recorded during the reproduction and arriving at one or more microphones within the spatial area.
