A user (102) hears an audio program being broadcast and can record a
sample of the audio. The sample is then conveyed to an analyzing means
(106) to determine to which broadcast station the user is listening. The
analyzing means monitors many broadcast channels. Thus, characteristics
of the audio sample and samples taken from the broadcast channels can be
compared to find a match. Broadcast information pertaining to the
broadcast channel from which the match was found may then be reported
back to the user, combined with an advertisement of a promotion, prize
notification, discount offers, and other information specific for a
certain radio station for example.
