BPM Detector & Tap Tempo
BPM Detector & Tap Tempo
Drop a song and get its tempo in seconds — or tap along on the button to measure any BPM by hand. Everything runs locally in your browser.
What BPM is this song?
Drop any track above and this free BPM detector analyzes its rhythm and tells you the tempo in beats per minute — usually within a couple of seconds. It listens for onsets (the attack of kicks, snares and hats), finds the strongest repeating pulse, and reports the BPM with a confidence rating plus the half-time and double-time alternatives.
How to find the BPM of a song
- Drop the audio file into the box (MP3, WAV, AAC, OGG, FLAC).
- Read the detected BPM — and check the half/double values, since 75 BPM and 150 BPM describe the same groove.
- Double-check by tapping the TAP button in time with the music.
Why BPM matters
Tempo drives everything downstream in a production: delay times, reverb pre-delay, LFO rates, quantize settings and how well two tracks mix together in a DJ set. Once you know the BPM, the Delay & Reverb Calculator converts it into exact millisecond settings, and the metronome lets you practice to it.
Electronic genres usually sit in known ranges: house 120–128, techno 125–135, dubstep around 140, drum & bass 170–175, trap and phonk commonly 130–160 (felt in half-time). If the detector reports 87.5 for a DnB tune, the real feel is 175.
FAQ
Is the BPM finder free?
Yes, free forever - no sign-up and no limits. The analysis runs on your device, so nothing is uploaded.
How accurate is the detection?
On music with drums it is typically within 0.1-0.5 BPM. The trickiest cases are rubato performances, ambient tracks without transients, and songs with tempo changes - for those, tap tempo is your friend.
Why does it show half or double the BPM I expected?
Tempo is ambiguous by nature: a 140 BPM trap beat can be felt at 70. The detector picks the strongest periodicity and always shows you the half/double alternatives so you can choose the musical one.
Can I detect the BPM of a long DJ mix?
The tool analyzes up to 90 seconds from the middle of the file for speed, so for mixes with changing tempo it reports the tempo around the midpoint. Cut a section with the Audio Cutter first if you need a specific part.
