1. A method of generating an impulse response from a speaker to a first microphone of a plurality of microphones of a multi-microphone device via one or more sound paths, the method comprising:
determining a plurality of sound paths to the first microphone of the plurality of microphones, wherein the plurality of sounds paths includes at least a first sound path and a second sound path;
generating a first auralized path for the first sound path to the first microphone and a second auralized path for the second sound path to the first microphone based on room simulator information, wherein
the room simulator information is generated based on the first sound path to the first microphone by determining n-th shortest sound paths from the speaker to the first microphone, wherein n is a counter of sound paths that have been determined; and
combining the first auralized path for the first sound path to the first microphone with the second auralized path for the second sound path to the first microphone to generate an auralized transfer function for the first microphone.
