Comment Comment by tim333 tl;dr they are archiving political ads off TV and try recognising them in software by their sound using http://labrosa.ee.columbia.edu/matlab/audfprint/ I think.They don't say how political ads sound different from other TV - I guess it works? Or maybe they are just using it to check if they have that ad already like how Shazam works? parent tim333 10 years ago
