Abstract: The present disclosure relates to a method of calculating an audio calibration profile for a three-dimensional space such as a room. The present disclosure achieves this by creating a model of the three-dimensional space using three-dimensional (3D) imaging techniques in conjunction with feedback from a sound recording device. The information gathered can be used by a digital signal processing (DSP) device to perform room equalisation. The information can also be used by beamforming audio sources to adjust beam characteristics to recreate the ideal spatial or surround sound experience at the user's location in the three-dimensional space.
