Score: 5.5/10 (Innovation: 6, Technical: 7, Documentation: 4, Utility: 5)

Legato is a realtime audio graph framework for Rust that combines a minimal DSL for defining audio processing graphs with the ability to write custom nodes in Rust. It takes inspiration from tools like PureData and SuperCollider but offers a unique workflow focused on flat allocation and direct mapping from DSL to runtime builder operations.

Target audience: backend devs, audio engineers, Rust developers
