ABSTRACT:
A method of classifying a spectro-temporal interval of an input audio signal (x(t)) is disclosed. A spectro-temporal interval of the input audio signal is first modelled (62 . . . 71) according to a perceptual model to provide a first representation (Rep1). The spectro-temporal interval is then modelled (62 . . . 71) using a modified noise substituted input signal according to the same perceptual model to provide a second representation (Rep2). The spectro-temporal interval is then classified as being noise or not based on a comparison of the first and second representations.
