Audio matching with semantic audio recognition and report generation

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

• a processor to:
• obtain the audio signature data of a first time period, the audio signature data including data relating to at least one of time or frequency components representing a first characteristic of media;
• obtain first semantic audio signature data for the first time period, the first semantic audio signature data being a measure of generalized information representing characteristics of the media;
• and
• memory to store 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.

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

• obtaining, by executing instructions with a processor, 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;
• obtaining, by executing instructions with the processor, 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;
• associating, by executing instructions with the processor, the semantic audio signature data to the audio signature data;
• and
• processing, by executing instructions with the processor, the associated semantic audio signature data and audio signature data to determine a change in the second characteristic relative to the first characteristic.
