Radio receivers have wireless communication to an associated smart phone, and transmit a copy of the audio output in digital format to an application in the smart phone. The smart phone application detects the beginning of a song, creates an acoustic fingerprint of the song, and obtains the artist and title of the song from an acoustic fingerprinting database of songs. The artist and title are delivered by the smart phone to the radio receiver, and are presented on the radio receiver's display screen. |
