It can add or remove instruments, change melodies, and even alter voice characteristics such as accent, emotion, and timbre. This level of manipulation opens up new possibilities for music production and remixing, potentially revolutionizing how artists and producers approach their craft.
Perhaps most intriguingly, Fugatto can produce novel and unique sounds that have never been heard before. As Rafael Valle, a manager of applied audio research at NVIDIA, explains, “Fugatto can make a trumpet bark or a saxophone meow. Whatever users can describe, the model can create.” This ability to generate entirely new sounds could have far-reaching implications for sound design in various industries, from film and television to video game development.
The model also showcases more technical capabilities, such as extracting vocals from a mix, morphing one sound into another, and converting MIDI melodies into realistic vocal samples. These features could prove invaluable in professional audio production settings, streamlining processes that traditionally required significant time and expertise.
Advanced Techniques and Innovations
Fugatto employs several advanced techniques that set it apart from other AI audio models. One such innovation is the use of ComposableART, a technique that allows the model to combine instructions not seen together during training. This capability enables users to create complex, multi-layered audio transformations that go beyond the model’s initial training parameters.
Another notable feature is temporal interpolation, which allows for the creation of evolving soundscapes. This means Fugatto can generate sounds that change over time, such as a rainstorm that gradually transitions into a peaceful dawn with birds singing. This level of dynamic sound generation opens up new possibilities for creating immersive audio experiences in various media.
The model’s ability to generate realistic speech and singing voices is another significant advancement. With fine-tuning and small amounts of singing data, researchers found that Fugatto could handle tasks it was not explicitly pretrained on, such as generating high-quality singing voices from text prompts. This capability could have profound implications for voice acting, dubbing, and music production.
