MediaTrak is a powerful extension to the passive behaviour toolset. It uses audio fingerprinting to listen out for audio which matches the library. This could be a Radio jingle, an advert on television, or a song being played. If the device can hear it then we can match it against a library of audio fingerprints.
Examples of how we have used this include to compare exposure to traditional advertising while also comparing against digital adverts via Tags on mobile and PC.
