It's all about the FREQUENCIES! Actually though, this system can be used to find copies of any sound -- sound bytes, commercials, music, whatever. We just happen to be using it for politics because we apparently hate fun. We're using the python port of audfprint though: https://github.com/dpwe/audfprint And yes -- we have a big bucket of known ads, and a big bucket of archived programming, and we're comparing new content with the appropriate buckets. NOTE: we are talking about ways to release the fingerprints of all the TV we archive so anybody can "search" TV for copies of sounds.
