key-detection
Dependency-free audio engine for C++, Python, Node.js & WASM: analysis, mastering, mixing, built-in instruments, and a headless-DAW runtime
Dissect a song's harmony from audio: chord recognition on the beat, key changes, Roman numerals, secondary dominants and borrowed chords.
Identify any song from a link or an audio file, then read its BPM, musical key and Camelot code — from your terminal or your code. Node.js and Python clients, zero runtime dependencies, no API key.
