Recently, the Beatles released a new song titled "Now And Then," which utilizes artificial intelligence to restore the voice of the late John Lennon. Originally composed by Lennon on piano in 1980, the song faced difficulties due to poor recording quality, making it challenging to isolate Lennon's voice. After the production team applied machine learning for audio denoising, Lennon's voice was finally presented clearly. This technology has enabled the Beatles members to complete this unfinished work, honoring their departed bandmate in a creative manner. Despite the controversies, this AI-assisted song represents a significant advancement in audio technology and should not be hindered by potential disputes.
