#### Why LUFS?

* **Multi-engine analysis** — each metric is detected by multiple independent engines that cross-validate results, giving you confidence scores alongside every value
* **Sub-10-second turnaround** — full analysis (BPM + Key + Hz + Loudness) completes in \~5 seconds on dedicated GPU hardware
* **10-stem separation** — split any track into vocals, instrumental, bass, drums, kick, snare, toms, hi-hats, and cymbals
* **Clean tagged MP3** — every analysis returns an MP3 file with embedded ID3 tags (BPM, Key, Hz) ready for your library or DAW
