Fraktur is a Rust port of the 'Beat This!' AI beat-tracking system, packaged as a CLI and library with a pure-Rust ONNX inference backend and a bundled small model. It is notable for its zero-setup, dependency-free deployment, streaming inference with bounded memory, and detailed documentation of numerical behavior across versions.

Target audience: Rust developers, audio/music software engineers, and researchers needing offline beat detection
