Claim:
1. A processor-based method for producing supplemental information for media containing an embedded audio code, the method comprising: obtaining an audio code from a device during a first time period, the audio code representing a first characteristic of the media, wherein the audio code is read from an audio portion of the media; obtaining first semantic audio signature data from the device during the first time period, the first semantic audio signature data being a measure of at least one of a temporal feature, a spectral feature, a harmonic feature, or a rhythmic feature relating to a second characteristic of the media; and associating the audio code of the first time period to a second time period when the processor determines that second semantic audio signature data of the second time period substantially matches the first semantic audio signature data for the first time period.
