Accurate within 1–2 BPM on tracks with a clear beat. Acoustic or highly syncopated material may return half- or double-time estimates.

Can it detect tempo changes?

No. This version returns a single global BPM. Splitting the file and running detection per section is a workaround.

What BPM range does it scan?

60–200 BPM. Outside this range, try halving or doubling the result manually.
