摘要： 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 (C1, C2, ..., Cn), each corresponding to a particular release-date information.
