An AI System For Editing Music in Videos (mit.edu) 31
Amateur and professional musicians alike may spend hours poring over YouTube clips to figure out exactly how to play certain parts of their favorite songs. But what if there were a way to play a video and isolate the only instrument you wanted to hear? MIT News: That's the outcome of a new AI project out of MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL): a deep-learning system that can look at a video of a musical performance, and isolate the sounds of specific instruments and make them louder or softer. The system, which is "self-supervised," doesn't require any human annotations on what the instruments are or what they sound like. Trained on over 60 hours of videos, the "PixelPlayer" system can view a never-before-seen musical performance, identify specific instruments at pixel level, and extract the sounds that are associated with those instruments.
For example, it can take a video of a tuba and a trumpet playing the "Super Mario Brothers" theme song, and separate out the soundwaves associated with each instrument. The researchers say that the ability to change the volume of individual instruments means that in the future, systems like this could potentially help engineers improve the audio quality of old concert footage. You could even imagine producers taking specific instrument parts and previewing what they would sound like with other instruments (i.e. an electric guitar swapped in for an acoustic one).
It's 'poring', not 'pouring' (Score:5, Informative)
Really? What substance do they pour over the clips? And to what end? Do they pour a liquid, like coffee? Or a fluid-like solid, like sand?
I'm sorry. Pouring vs poring is one that really bugs me, for some reason.

What's especially pathetic is that Trump is being mocked world-wide for making the same error in a tweet recently, and slipshod.org here just copied his embarrassing mistake, bigly. Sad!

Which is all this is going to be good at, because every time you pluck a string or play any musical instrument really, every note is subtly different... Unless you are talking about digital playback of samples, which is identical every time. You can hear the difference between a drum machine and a drummer as a consequence.

This sounds like the system is combining object recognition of musical instrument and processing the audio in order to separate the musical instruments. But that's not the hard part. A middle school band student can provide a list of the instruments in a video. The hard part is going to be separating the instruments in a way that sounds good.
As for previewing the same line on a different instrument, that's what MIDI is for. The issue would be the quality of the samples used.

Have a new band play in front of the AI to see if they can make a music video that will sell bas ed on past sales.
Eye contact, movement, voice, dancing, walking, running, clothing. To smile, not to smile. The lyrics. The energy and skill put into performing.
The ability to perform to the style that is selling at that point in time.
The artist who has decades of new sales.

Do you write your posts in Mandarin using a brick, then OCR them and translate them manually into Welsh then dictate them to someone from New Guinea who types them in for you?

Why would you use a band? Use AI and biofeedback, play music at people digitally and genetically evolve it. Much easier than involving excess humans in the process. Even Trent Reznor doesn't like humans because they make mistakes, imagine how much it will slow down an AI :)

I'm sure they can be fooled by playback, when the musicians only fake the playing.

would be to use it to remove annoying background irrelevant heavy metal music that people add to their favorite movie clips so you can actually watch and hear the real in-movie clip without the annoying distraction.
Also, on Twitch (and YT) many clips either get muted by the service because of copyright claims. Having this feature could strip out the offending sound but leave the streamer's voice (and room sounds) unscathed. Everyone wins.
