Artificial Intelligence is the new face of revolution, and practically every segment is revving up its consumable wave. Beginning from the music industry to the films, business, and finance caveat, AI’s surge is palpable. The latest is its recent exploration in the famous cartoon Chainsaw Man.
Kensuke Ushio, the principal composer of Chainsaw Man, uses a song that is part of the anime’s official soundtrack to illustrate his ideas about AI and human interaction. A short 2023 Sony documentary about Ushio’s use of AI for a song in Chainsaw Man was made famous by X (formerly Twitter) user @kles7_.
ChainsawGAN, the new AI tool
The AI tool “ChainsawGAN” was created by Sony Computer Science Laboratory (Sony CSL) and Ushio expressly for the series’ soundtrack, as mentioned in the documentary. Interviews with Sony CSL’s Javier Nistal and Ushio delve into the inner workings of ChainsawGAN and future possibilities. See the trailer for the documentary below, which also includes a clip of Ushio’s AI-transformed song “Chainsaw Attacks!”
The video’s chainsaw sound effects were modeled after common percussion sounds. ChainsawGAN is capable of taking a variety of sounds and transforming them into “dimensions” that produce distinct spectrums from which sounds can originate. Changing the sound of a kick drum to that of a chainsaw is one example. According to Ushio, AI could inspire him to be creative in a way that he might not have been able to come up with on his own. He wanted to convey the “messed up” sense in Chainsaw Man.
Because ChainsawGAN can fill in any gaps in the melody that humans couldn’t think of, I proposed having it learn chainsaw sounds instead of human voices,” Ushio said, “I’ll extract the drum sound and turn it into data for a musical score. Is that correct? Ta-tatto-ta-tatto-ta-ta-ta-to? I’m translating it into musical notes that sound this way the moment the drums are hit in this particular manner.” The sound heard above was produced by him feeding ChainsawGAN the musical notes.
Ushio’s viewpoint on AI becomes crucial because he is a well-known anime composer who created the soundtracks for shows like Heavenly Delusion, Devilman Crybaby, A Silent Voice, and the upcoming Dandadan anime adaptation. It doesn’t seem like ChainsawGAN can verify whether sounds were obtained lawfully, and Ushio asserts that the issue of “rights” over sounds and creativity should be kept apart first.
The question of legality as AI infiltrates Anime
Ushio argues that everyone who hears something ought to have the opportunity to explore the creative output that results from it. “The creativity of the composer being expressed,” he contends, should be evaluated.
In his ideal world, everyone would have access to the sounds they hear in their heads and the inspiration that follows; the important thing is to judge how these sounds are combined.
Creativity is a thing of so much controversy, and it is much more vulnerable when it is entangled with artificial intelligence; the recent boom in the market is pushing many to question the availability of regulations that will safeguard copyright and prevent devastating plagiarism. It will be interesting to see how AI interacts with soundtracks on Anime and movies in the coming months.
