Abstract:
1. A method of simulating an ideal virtual channel position in an audio system, said method comprising: broadcasting at least one calibration audio signal through each of a plurality of speakers (M) in said audio system; receiving the calibration audio signal in a plurality of microphones spaced apart and positioned at a predetermined listening position; calculating a speaker placement angle relative to said predetermined listening position, wherein said angle is determined using an impulse response to said calibration audio signal, and wherein said angle is calculated between each of said plurality of speakers (M) and said plurality of microphones; determining a multi-planar angular location for each of said plurality of speakers (M) in relation to said listening position to facilitate a simulation of an ideal virtual channel position; rotating a sound field using at least a parameter obtained from a calculation of the angular location relative to said listening position; and amplifying at least a virtual output audio channel amplitude vector through said plurality of speakers (M) thereby rotating said sound field.
