Just had an interesting call from Radio Research, who after talking for a while want me to take part in radio research by adding an app to my smart phone. The app is supposed to hear what music is being played in your car or in your home or where-ever you are.
It listens to hidden codes in the music which is then transmitted weekly to the agency for analysis.
It only detects music that has the codes embedded and nothing else.
Has anyone heard of this type of audience research. Here is a url http://nz.ipsosmediacell.com/Introduction.html that explains how it works. Incidentally they pay for your time. Not sure I want to do this but the idea of how it works is intriguing. Certainly an improvement on the old diaries
