What does the BPM Detector do?
It analyzes an uploaded audio track and estimates its tempo in beats per minute.
How accurate is the detected BPM?
Tempo detection is an estimate based on the track's rhythmic pattern — it works best on tracks with a clear, steady beat, and may be less precise on tempo-varying or ambient audio.
Where is my audio file processed?
