Optional — improves beat accuracy

Best results: Works well on songs with a consistent tempo and a single time signature throughout. Chord detection is based on audio analysis and may not be perfect on dense arrangements or songs with rapid key changes. For best accuracy, use a clean mix rather than a live recording with crowd noise.
