Nvidia says its new AI music editor can create “sounds never heard before” — like a trumpet that meows. The tool, called Fugatto, is capable of generating music, sounds, and speech using text and audio inputs it’s never been trained on.

While some AI models can compose a song or modify a voice, none have the dexterity of the new offering. Called Fugatto (short for Foundational Generative Audio Transformer Opus 1), it generates or transforms any mix of music, voices and sounds described with prompts using any combination of text and audio files. For example, it can create a music snippet based on a text prompt, remove or add instruments from an existing song, change the accent or emotion in a voice — even let people produce sounds never heard before.
