Frequently asked questions
How accurate is the BPM detection?+
For music with consistent steady-state tempo (electronic, pop, rock), accuracy is typically within ±1 BPM. For variable-tempo recordings (live performances, orchestral music, free-form jazz), the detector returns the dominant tempo but may miss tempo variations. For professional DJ use, always verify the detected BPM by ear.
Can BPM detection work on speech or podcast audio?+
BPM detection requires periodic rhythmic content. Speech and podcast audio without a music bed will typically return unreliable BPM values. The tool is designed for musical content with a consistent beat or pulse.
What BPM range does the detector support?+
The detector works reliably in the 60–200 BPM range, which covers most popular music genres. Very slow music (below 60 BPM) and very fast music or drum solos (above 200 BPM) may be reported at half or double the actual tempo due to the ambiguity of beat period detection at extreme tempos.
