BPM tapper and delay times
Tap the big button along with the beat to find the tempo, or type a BPM you already know. You get the milliseconds for each note length, straight, dotted and triplet. Taps only; no audio is used.
Key takeaways
Taps only
The tool counts your taps. It does not listen to or upload any audio.
One beat = 60,000 ÷ BPM ms
At 120 BPM a beat is 500 ms, an eighth note 250 ms.
Dotted ×1.5, triplet ×⅔
The table works these out for you for every note length.
The math
- Milliseconds per beat = 60,000 ÷ BPM. 120 BPM is 500 ms; 90 BPM is about 666.7 ms.
- Note lengths are fractions of a beat. A quarter note is one beat, an eighth half a beat, a sixteenth a quarter, and a whole note four beats.
- Dotted notes are 1.5× longer; triplets are ⅔ as long.
Questions people ask
How does a BPM tapper work?
You tap along with the beat. The tool averages the time between your recent taps and converts it to beats per minute: 60,000 divided by the average milliseconds between taps. A gap of more than two seconds starts a new count.
How many taps do I need?
Two taps give a first reading, but about eight or more steady taps are more accurate. The tool uses your most recent eight.
How do I turn BPM into delay milliseconds?
One beat lasts 60,000 divided by BPM milliseconds. A quarter note is one beat, an eighth is half a beat, and so on. Dotted notes are 1.5 times as long and triplets are two thirds as long.
Does it listen to my music?
No. It only counts your taps. No audio is used or recorded, and nothing is sent anywhere.
Why does my result jump around?
Uneven tapping moves the average. Keep tapping steadily, press Reset to start again, or type the tempo you know to see the delay table.
