- tenebrisalietum 6y agoIf human beings can tell the difference between speech and background audio while both are playing simultaneously, it has to be possible somehow for a machine to do it.
- thaumasiotes 6y agoThis is certainly something that humans do, but they do have a significant error rate.
- Udik 6y agoGiven that copyrighted audio is- more or less by definition- available as a separate track without interference, it shouldn't be too difficult to subtract it from the video's track.
- thaumasiotes 6y agoIt's theoretically straightforward if you have the actual copyrighted audio; you can just invert it and add it to the audio stream. But I believe YouTube stores some kind of digest related to the audio they identify, not the audio itself. Then again, that audio is available for many pieces that happen to be present in other videos on YouTube, which ContentID would automatically identify.

I mean, thinking of a hack. I could distribute two sound files that alone don't sound like anything much, but if you run them through such an inverter, it produces a copyrighted song. I'd guess the legal system would jump on me and claim one of my files has a music-shaped-hole in it that infringes on the original work.

I could see that kind of technology could be adapted to this use case not because it's right or wrong, but because there's an incentive for the platform to leave the content up and able to be monetized rather than 86'd entirely.
- Mashimo 6y agoThere was a time when they did that. I had a video with music from The Doors and people talking over. They removed the song and you could still hear the distorted voices
