EFFICIENT APPARATUS AND METHOD FOR AUDIO SIGNATURE GENERATION USING RECOGNITION HISTORY

Audio information is monitored by a user device by generating audio signatures of ambient audio content captured by the user device, receiving conditions of the user device that were present when the ambient audio content for each audio signature was captured, performing audio content recognition on the audio signatures by comparing in a query engine the generated audio signatures to audio signatures previously stored in a database associated with the query engine, identifying generated audio signatures that match audio signatures stored in the database within a threshold confidence level, thereby establishing successful audio content recognition, identifying the conditions of the user device that were present for successful audio content recognition, generating scheduling rules regarding the conditions present during successful audio content recognition and controlling when the user device captures audio content and/or generates audio signatures based on the scheduling rules.
