BPM Detector

Estimate the tempo of any music track. The tool decodes the audio, computes short-term energy windows, detects energy peaks (onsets), then runs interval analysis to find the dominant beat period and converts it to BPM.

How accurate

Results are typically within ±2 BPM for music with a strong, regular pulse. Songs with weak transients, complex rhythms, or rubato may produce lower confidence scores.

Use cases

• DJ track preparation
• Music library tagging
• Sample collection organization
• Workout playlist sorting
• Songwriting reference
