Could you build this?
No Extracting key, BPM, microtuning, loudness (LUFS), and dynamic beat grids locally and accurately requires deep digital signal processing (DSP) and specialized audio engineering.
What it would actually take: Building this requires a native macOS app (Swift/C++) integrating advanced audio DSP libraries (such as Essentia, Aubio, or custom FFT/chromagram implementations) and ITU-R BS.1770-4 loudness measurement filters. The hard parts are robust onset detection, beat-tracking algorithms resilient to non-quantized tempos, chord/chroma-based harmonic analysis for key-finding, and optimizing real-time audio analysis locally to execute in seconds without high CPU overhead.
