8. A system for producing supplemental information for media containing embedded audio codes, wherein the codes are read from an audio portion of the media, comprising: an input configured to receive the audio codes from a data network, said audio codes being received from a device during a first time period, wherein the audio codes representing a first characteristic of the audio portion; said input being further configured to receive semantic audio signature data from the data network, said semantic audio signature data being received from the device for the first time period, wherein the semantic audio signature comprises at least one of temporal, spectral, harmonic and rhythmic features relating to a second characteristic of the media content; and a processor, operatively coupled to the input, said processor being configured to successively associate the semantic audio signature data to the audio codes in a processor for the first time period.
