Abstract: A method of determining on a computer-based system at least one representative segment of a musical composition, the method including providing a digital audio signal representing said musical composition; dividing said digital audio signal into a plurality of frames of equal frame duration; calculating at least one audio feature value for each frame by analyzing the digital audio signal, said audio feature being a numerical representation of a musical characteristic of said digital audio signal, with a numerical value equal to or higher than zero; identifying at least one representative frame corresponding to a maximum value of said audio feature; and determining at least one representative segment of the digital audio signal with a predefined segment duration, the starting point of said at least one representative segment being a representative frame.
