How to find the BPM of a song
Drop any audio file into the analyzer above and you'll get its tempo in seconds. The BPM finder scans the low end of your track — where the kick drum and bassline live — finds the energy peaks, and measures the time between them. Because everything runs locally in your browser, there's nothing to install, no account to create, and your music is never uploaded to a server.
Why BPM matters for musicians and creators
Knowing your track's exact tempo is essential for DJs beatmatching two songs, producers setting a project tempo before adding samples or loops, and dancers building choreography. It's just as important for video: edits that cut on the beat feel dramatically more professional. That's exactly what our AI music video generator does automatically — it detects your song's BPM and syncs every scene change, transition, and effect to the rhythm.
Common BPM ranges by genre
Hip-hop usually sits between 80–100 BPM (trap often at 130–150 with half-time feel), house music at 120–128, techno at 125–135, drum & bass at 160–180, pop between 100–130, and lo-fi around 70–90. If your detected BPM seems double or half of what you expect, that's normal — the same rhythm can be counted both ways, which is why we show the half-time and double-time values too.
