Paul McCartney announced that he's finished using AI to clean up a recording of Lennon's vocals for a brand new track. For Beatles fans, this is like Christmas. But the use case may also be a perfect demonstration to the rest of the industry of how AI can be used, not to replace the artist, but as a revolutionary tool in bringing back to life lost or damaged work. After Peter Jackson used AI to help Paul McCartney duet with John Lennon during Glastonbury last year, the legendary musician asked for his help in creating one last Fab Four song.                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                  AI wasn't used to recreate Lennon's voice, but instead took an old demo of Lennon's, isolated his voice from the instruments being played, and made his voice "pure". McCartney was then able to mix the record like normal. While McCartney says he's just as amazed and terrified of AI as anyone, in his hands, it's just another instrument helping to create some very human magic.
