as with all ML things... the code is much less % of the value than the data...

Perhaps obviously this is the same technique that enables ACR on TVs.

It occurs to me that Shazam has such a better reputation online because the intent and consent of the user is honored.

It makes me wonder if there couldn’t be an implementation on TVs that is similar and actually is a net positive for consumers. Basically would customers actually like TV ACR if the data wasn’t just going to sell more ads?

So the value-add would be the consumer would get to find out the name of the show or movie that’s playing, the same info that also pops up if they hit the pause button?

I was thinking more like interactive content. Do you remember when VH1 had a pop-up music video show?

Shows could synchronize additional content that’d be visible when Shazam mode enabled.

		Pop. Pop. Pop Up Video.

Recognizing a recording isn't hard to do, because, for the same recording, the chords follow each other with precisely repeatable timing. That's been around for well over a decade. Recognizing a different recording, say, a, cover version, of the same song, is much more work.

Audible Magic claims to be able to recognize multiple performances of the same songs, and even parodies.[1] Using, of course, "AI technology" and much more compute.

		20 years at least. I remember seeing how Gracenote worked back in the day when I was consulting for them.

		Why is this harder than "delete timing information" ?

Forgive my ignorance, but what does SCP mean in this context? (my normal go-to of 'secure copy' doesn't fit).

Thanks for the other links, the question in this title is one I've day-dreamily thought about on occasion, but never dug into. Will have a read of all three.

Vaguely relevant pop-culture reference.[1]

		I seem to have wandered into a parallel universe. I think it'll take me longer to understand WTF SCP is than it will to understand how Shazam works.

The interactive parts of this post are very cool though

Out of curiosity is it possible to prevent shazam like app from detecting maybe by adding noise or any technique ?

Add to my list of projects. Dinosaur game but with audible clucks to jump.
