Audio matching with semantic audio recognition and report generation

A apparatus for producing supplemental information for audio signature data, the apparatus including:

• a processor to:
• obtain the audio signature data at an input from a data network, the audio signature data received from a device, the audio signature data including data relating to at least one of time or frequency components representing a first characteristic of media;
• obtain semantic audio signature data at the input from the data network, the semantic audio signature data received from the device, the semantic audio signature data being a measure of at least one of a timber feature, a beat feature or a pitch feature relating to a second characteristic of the media;
• associate the semantic audio signature data to the audio signature data;
• and
• process the associated semantic audio signature data and audio signature data to determine a change in the second characteristic relative to the first characteristic.

An article of manufacture comprising instructions that, when executed, cause a processor to at least:

• obtain the audio signature data at an input from a data network, the audio signature data received from a device, the audio signature data including data relating to at least one of time or frequency components representing a first characteristic of media;
• obtain semantic audio signature data at the input from the data network, the semantic audio signature data received from the device, the semantic audio signature data being a measure of at least one of a timber feature, a beat feature or a pitch feature relating to a second characteristic of the media;
• associate the semantic audio signature data to the audio signature data;
• and
• process the associated semantic audio signature data and audio signature data to determine a change in the second characteristic relative to the first characteristic.
