About BPM and Tap Tempo
BPM (Beats Per Minute) is the standard unit for measuring musical tempo — the speed of a piece of music. One beat is the basic pulse you naturally tap your foot to. At 120 BPM there are exactly 120 of those pulses every minute, or one every 500 milliseconds.
Knowing the BPM of a track is essential for DJs (to beat-match tracks), producers (to sync samples and loops), and live musicians (to set a metronome correctly). The tap tempo method — tapping in time with the music — is the fastest and most accurate way to find BPM by ear.
The delay values table shows how long each note subdivision lasts in milliseconds at the detected BPM. These values are used in audio plugins — particularly delay and echo effects — to sync the effect to the music. A quarter-note delay at 120 BPM = 500ms; a dotted eighth = 375ms.
Frequently Asked Questions
How do I use the BPM tapper?
Tap the big button or press any key in time with the beat of the music. After 4 or more taps the BPM will appear. Keep tapping to refine it. Click Reset to start over.
Why does my BPM keep changing?
The BPM is a rolling average of your recent taps. It naturally stabilises after 6–8 consistent taps. Tap along with the kick drum — it's the most regular element of most songs.
What are the delay values?
The delay table shows how long each note length lasts in milliseconds at your current BPM. Use these to set delay/echo plugins in your DAW so the effect is in sync with the song.
What is a dotted note delay?
A dotted note is 1.5× the length of its base note. A dotted quarter note at 120 BPM = 750ms (instead of 500ms). Dotted eighth note = 375ms. These are very commonly used in music production for a rhythmic slapback echo effect.
How accurate is tap tempo?
After 8 consistent taps, tap tempo accuracy is typically ±1 BPM. The more taps you make, the more the average smooths out small inconsistencies in your tapping. Professional DJs and producers use this method routinely.
