Analyzing YouTube's Audio Fingerprinter
Al Benedetto writes "I stumbled across this article which analyzes the YouTube audio content identification system in-depth. Apparently, since YouTube's system has no transparency, the behaviors had to be determined based on dozens of trial-and-error video uploads. The author tries things like speed/pitch adjustment, the addition of background noise, as well as other audio tweaks to determine exactly what you'd need to adjust before the fingerprinter started mis-identifying material. From the article: 'When I muted the beginning of the song up until 0:30 (leaving the rest to play) the fingerprinter missed it. When I kept the beginning up until 0:30 and muted everything from 0:30 to the end, the fingerprinter caught it. That indicates that the content database only knows about something in the first 30 seconds of the song. As long as you cut that part off, you can theoretically use the remainder of the song without being detected. I don't know if all samples in the content database suffer from similar weaknesses, but it's something that merits further research.'"
It's a good thing no one at Youtube reads Slashdot. Otherwise they might come up with a fix! So, everyone keep this a secret! SHHHH!

Sounds like packaging copyright material between thousands of papers and delivering it in PDF format to my university printing service to print out all my textbooks for free... except with less wasted paper.
Heh. I think people have already tried that.
Hi, I'm am amateur movie critic. Today I'm going to show you an example of poor film-making. blah blah blah ...
*Plays entire Star Wars: Episode I*
So, as you can see by the [cinematography jargon] and [screen writing jargon], this movie sucked and I hope you learn from it in making your own movies.
One week later:
"No! You can't take down my video. This is CLEARLY fair use, since I have OBVIOUSLY used it for educational commentary, and the entire clip was VITAL for showing how much Episode I sucked."
Information theory is life. The rest is just the KL divergence.
Here's an idea. Start out the video with a useless narrative for the first thirty seconds "blah blah blah skip until :30 and ignore this intro blah blah" then start the music.
Like on the radio?
