Abstract
A method for creating a multichannel audio signal that provides the impression of spatial sound is disclosed, the method comprising providing an expected multichannel audio output signal having spatialised soundfield components; perturbing the spatial components; and utilising the perturbed spatial components to determine the multichannel audio signal. The perturbations can be substantially in accordance with the expected head movements of listeners of the audio signal and can be derived from a group of listeners to the audio signal. The expected head movements also preferable include an added substantially random movement.
