Abstract:
1. A computer-implemented method for operating a computer having a processor to analyze the quality of a multi-channel audio test signal, comprising: (a) determining a plurality of audio spatial cues for a plurality of different pairings of channels in the multi-channel audio test signal; (b) determining a corresponding plurality of audio spatial cues for a corresponding plurality of the different pairings of channels in a multi-channel audio reference signal distinct from the multi-channel audio test signal; (c) comparing the determined audio spatial cues of the plurality of different pairings of channels in the multi-channel audio test signal to the audio spatial cues of the corresponding plurality of different pairings of channels in the multi-channel audio reference signal to produce comparison information; and (d) determining, at the processor, a computational measure of the audio spatial quality of the multi-channel audio test signal based on the comparison information.
