Audio matching

Audio matching is a technical method for measuring audiovisual content. In the AGF Panel with the UMX measurement system, it has been used in the panel households since 08/01/2012 to survey the television usage of panel members. Under the audio matching method, audio signals in the television set are captured in the form of audio patterns and continuously checked against programmes stored in a server. Matching signals are then assigned to a TV broadcaster. If content cannot be clearly assigned to a broadcaster (for example, if the programme is broadcast simultaneously on several channels), additional information such as the regional reception spectrum or infrared codes are used to make the assignment.
