Dear Auditory List,
In the upcoming future I begin a project focused on creating a small driver
aimed to control home devices. It will be voice-controlled, hence a small
microphone matrix have to be implemented in it. I’ve made some preliminary
research in the topic of matrices, but I haven’t found an answer to my most
important question: is there any equation or, let’s say, ‘simple law’, which let
estimate angular resolution (both horizontally and vertically) of the matrix
regarding number of microphones and geometry between them? Maybe you can advise
me something or just point out papers and research which I should analyze? And
what about programming it effectively using real-time processing? I will
probably use MEMS microphones, maybe this information helps you somehow. I will
really appreciate your help.
