A method for identifying an audio signal from a set of audio signals. A user preference (106) is received (104). The set of audio signals is concurrently received (108), for example from a number of radio sources. The audio signals are analysed (110) to extract features (112). Audio signals are identified (114) based on a comparison of the user preference (106) and extracted features (112). Optionally, the identified audio signals are outputted (116).
