Legato

A realtime audio framework and domain-specific language for building audio applications in Rust that handles graph definition and audio processing orchestration. It is for developers building audio software who want to define processing graphs without learning separate audio languages. It is positioned against tools like PureData, SuperCollider, FunDSP and MaxMSP with a minimal DSL that maps directly to runtime builder operations and allows custom nodes and reusable patches written in Rust with flat allocation.
