An system for determining time offset of an audio signature from a reference signature time stamp may have a server connected to one or more remote devices. The server may have a receiver connected to one of more communication channels configured to receive an audio signature generated by the remote device and transmitted over the communication channel. The system may have a database at or connected to the server that contains one or more reference audio signatures. Each of the reference audio signatures may have a time stamp also stored in the database. A query engine may compare the remote audio signature to one or more reference audio signatures stored in the database. A processor may be provided to compare a reference timestamp to a timestamp associated with said remote audio signature. The system may be used to evaluate viewing habits and particularly delayed viewing and program playback manipulation such as Fast-forward, slow-motion, skip, rewind and program abandonment.

Apparatus and method for determining audio and/or visual time shift

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 sound level at a user device and refraining from audio monitoring and/or generating audio signatures when the sound level is below a threshold. Sound level 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.
