Abstract: There is an apparatus for evaluating the audio quality of a multi-channel audio codec, including: a preprocessing unit for synthesizing binaural signals based on multi-channel audio signals transmitted through a multi-channel of a multi-channel audio reproduction system; an output variable calculator for calculating an interaural cross-correlation coefficient distortion (IACCDist) and other output variables of the binaural signals; and an artificial neural network circuit for outputting a grade of the perceived quality based on the interaural cross-correlation coefficient distortion (IACCDist) and other output variables calculated in the output variable calculator.
