In our project we implemented and improved a method to perform
audience measurements using audio sampled by mobile phones. The idea is to sample data from mobile phones and compare the sampled data with data sampled from known broadcasting source. We implemented an algorithm introduced in a paper by Covell & Baluja in 2006. The method in this project differs from most known methods by using image processing methods in order to create the audio samples fingerprints. The performance of the algorithm was tested in simulations checking the audio matching capabilities under several distortions.
