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.
