The invention describes a method of classifying an audio input signal ( 1 ), said method comprising the steps of extracting a number of features ( 2 ) of the audio input signal ( 1 ), deriving a feature vector ( 3 ) for the input audio signal ( 1 ) based on these features ( 2 ), and determining the probability that the feature vector ( 3 ) for the input audio signal ( 1 ) falls within any of a number of classes (C 1 , C 2 , . . . , Cn), each corresponding to a particular release-date information.
