Abstract

Systems and methods are provided for gathering audience measurement data relating to receipt of and/or exposure to audio data by an audience member. Audio data is monitored to detect a monitoring code. Based on detection of the monitoring code, a signature characterizing the audio data is extracted.

Claims

1. A method of gathering data reflecting receipt of and/or exposure to audio data, comprising:

receiving audio data to be monitored in a monitoring device, the audio data having a monitoring code indicating that the audio data is to be monitored;

detecting the monitoring code; and

in response to detection of the monitoring code, producing signature data characterizing the audio data using at least a portion of the audio data containing the monitoring code.
