Efficient apparatus and method for audio signature generation using motion

摘要

An automatic content recognition system that includes a user device for the purpose of capturing audio and generating an audio signature. The user device may be a smartphone or tablet. The system is also capable of determining whether a user device is in motion and refraining from audio monitoring and/or generating audio signatures when the user device is in motion. Motion may also be used to reduce the frequency of audio monitoring and/or signature generation. The system may have a database within the user device or the user device may communicate with a server having a database that contains reference audio signatures.

1. An apparatus for monitoring audio information comprising:
a probe component to capture audio information; a motion detector; an audio signature generator responsive to said probe component and said motion detector, wherein the audio signature generator is configured to generate audio fingerprints when the motion detector does not detect motion and to inhibit generation of audio fingerprints when the motion detector detects motion, and wherein the audio fingerprints represent audio content; and a transmitter, responsive to the audio signal generator, that transmits the audio fingerprints over a communication channel to a remote server for potential identification of the audio content represented by the audio fingerprints.
