We were blown away by the community interest in our Riffusion experiment (see <a href="https://www.riffusion.com/about" rel="nofollow">https://www.riffusion.com/about</a>).<p>We're now catching up and did a full rewrite to go from a hack to a quality software project. It also includes an extensible CLI tool and an interactive streamlit app for common tasks, MPS backend support, stereo spectrogram encoding, a test suite run by CI, and more. These tools provide a solid foundation to build upon.
