An analysis may report 70 BPM for a song a musician counts at 140 BPM. These can describe different beat levels. Tap along, count for 15 seconds and multiply by four to compare with the musical pulse.

Limits that affect the result

Key and BPM are estimates. Speech, isolated percussion, nonstandard tuning and tempo changes may prevent a reliable answer.
