It&#x27;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.<p>We&#x27;re using the python port of audfprint though: <a href="https:&#x2F;&#x2F;github.com&#x2F;dpwe&#x2F;audfprint" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;dpwe&#x2F;audfprint</a><p>And yes -- we have a big bucket of known ads, and a big bucket of archived programming, and we&#x27;re comparing new content with the appropriate buckets.<p>NOTE: we are talking about ways to release the fingerprints of all the TV we archive so anybody can &quot;search&quot; TV for copies of sounds.
