How many taps do I need for an accurate reading?

You get a first estimate after 2 taps. The tool uses a rolling average of up to the last 8 taps, so 6 to 8 steady taps give a reading within 1 BPM of the true tempo. Using the Spacebar is typically more precise than clicking.

What is a dotted note subdivision?

A dotted note is 1.5 times the length of the undotted note — a dotted quarter equals three eighth notes. Dotted values are commonly used in swing rhythms and to create rhythmic tension.

How are triplet timings calculated?

A triplet divides the parent note into 3 equal parts instead of 2. For example, a quarter-note triplet lasts two-thirds of a beat: (60000 / BPM) * (2/3) milliseconds. The table lists the duration of one note within the triplet group.

Why does the session reset after I stop tapping?

Any gap longer than 3 seconds between taps is treated as a new session. This prevents a long pause from distorting the rolling average with an enormous interval value.

Can I type in a BPM instead of tapping?

Yes. Enter any BPM value (20–300) in the manual input field and press Enter or Tab. The subdivision table updates immediately without affecting any tap history.

Summary

This tap tempo calculator computes your BPM from live taps and immediately breaks down every common note subdivision — whole, half, quarter, eighth, sixteenth, and 32nd notes, each in straight, dotted, and triplet forms — as precise millisecond values. It is designed for producers, mix engineers, and musicians who need exact timing values for DAW settings, delay units, or rhythmic programming.

How it works

Tap the TAP button (or press Spacebar) in time with the beat of your music.
After 2 taps the BPM appears. The rolling average of up to 8 taps refines the reading as you continue.
Or type a BPM directly into the manual input field and press Enter.
The subdivision table updates instantly, showing millisecond durations for whole, half, quarter, eighth, sixteenth, and 32nd notes — plus straight, dotted, and triplet variants.
Use Reset to clear the session and start fresh, or simply pause tapping for 3 seconds.

Use cases

Set delay, reverb pre-delay, or LFO rates in a DAW to perfectly match the song tempo.
Confirm the BPM of a reference track before mixing or producing.
Calculate exact note lengths for MIDI quantization or loop chopping.
Match rehearsal metronome speed to a recorded track.
Calculate triplet timings for polyrhythmic drum programming.
Coordinate lighting or video effect pulses to a live performance BPM.
