Abstract
A method for the creation of acoustic impulse responses for utilization in rendering to an array of speakers comprising the steps of measuring a room response function; extracting a series of discrete time arrivals from the measured room response function so as to have a reverberant residual response function; separately rendering the extracted series and the reverberant residual response function to the array of speakers to form a discrete response and a residual response; combining the discrete response and the residual response to form an acoustic impulse response for the array of speakers.
