1. A processor-based method for producing supplemental information for audio signature data, comprising:

  • obtaining the audio signature data during a first time period, the audio signature data including data relating to at least one of time or frequency representing a first characteristic of media;

    obtaining first semantic audio signature data for 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

    storing in a memory, the audio signature data of the first time period in association with a second time period when the processor determines that second semantic audio signature data for the second time period substantially matches the first semantic audio signature data for the first time period.
