Classification: CPC G  H | IPC G  H

Claim 18:
19. A method of detecting binauralization of an audio signal, the method comprising:
receiving an input audio signal;
extracting, by a feature extractor, a plurality of features from the input audio signal;
performing, by a classifier, a classification of the plurality of features extracted by the feature extractor;
generating, by the classifier, a result based on the classification, wherein the result indicates a probability that the input audio signal is a binaural signal;
performing virtualization, by a virtualizer, on the input audio signal to generate a binaural audio signal; and
generating, by a mixer, an output audio signal according to the result,
wherein when the result indicates that the input audio signal is not the binaural signal, the output audio signal corresponds to the binaural audio signal, and
wherein when the result indicates that the input audio signal is the binaural signal, the output audio signal corresponds to the input audio signal.
