Patent ID: 8005228

Claim:
A method for correcting room acoustics at multiple-listener positions, the method comprising: measuring with a microphone a room acoustical response at each listener position in a multiple-listener environment; processing each of the room acoustical response measured at said each listener position to obtain non-uniform resolution of the room acoustical response in an audio frequency domain, wherein the non-uniform resolution results in higher resolution at low frequencies for each of the measured room acoustical response; determining a general response by computing a weighted average of the processed acoustical responses; generating a low order spectral model of the general response; obtaining an acoustic correction filter from the low order spectral model, wherein the acoustic correction filter is the inverse of the low order spectral model; and processing the acoustic correction filter to obtain a room acoustic correction filter with uniform resolution in the audio frequency domain; wherein the room acoustic correction filter corrects the room acoustics at the multiple-listener positions.
