A method of generating a user profile ( 7;17,19;29 ) of a user of a device ( 14,15;23 - 26 ) for processing data representative of items of content, a respective recording of at least one perceptible content element being associated with each item of content, includes determining a set ( 3 ) containing a plurality of recordings of at least one perceptible content element, each associated with one of a plurality of items of content associated with the user, and generating data representative of a user profile ( 7;17,19;29 ) associating preferences of the user with the user, wherein the data representative of the user profile ( 7;17,19;29 ) includes one or more parameter values within an at least one-dimensional feature space, each dimension representing a property of at least a section of a recording of at perceptible content element, such that at least one of the dimensions in the feature space represents a quantifiable property of at least a section of a perceptible content element. At least one set of parameter values, each set containing at least one parameter value and quantifying a dimension of the feature space in the user profile ( 7;17,19;29 ), is obtained by applying a pre-determined analysis algorithm to each of a plurality of signals, each signal representing at least a section of a recording of at least one perceptible content element, such that the set of parameter values is based on a plurality of the recordings in the set of recordings.
