Why it’s interesting
The Beatles' final new song used machine-learning audio separation developed through Peter Jackson's production work to isolate John Lennon's voice from an old recording. The surviving members and production team then completed the track.
The important distinction is audible and historical: this is not a newly generated fake Lennon performance, but a real recorded voice recovered from noisy source audio.
How to try it
Watch the official music video and read the Beatles' announcement. Separate the voice-isolation technology from generative voice synthesis when describing what the system did.
Use the official page or demonstration as the current reference. Do not assume that a staged installation, limited experiment, account-gated demo, subscription feature, or physical product is available everywhere.
