BPM Calculator — Tap Tempo and Note Duration Reference for Musicians

The BPM Calculator is a tap tempo detector and note duration reference table for musicians, producers, and sound engineers. Tap any key repeatedly to detect the tempo of a song, or enter a BPM value manually to calculate exact millisecond durations for every note subdivision.

The tool measures the intervals between your taps, averages them, and converts the result to beats per minute. It then computes durations in milliseconds for whole notes, half notes, quarter notes, eighth notes, sixteenth notes, triplets, dotted notes, and more. These values are essential for configuring delay effects, setting loop lengths, and programming MIDI sequences with surgical precision.

Music producers use BPM Calculator to match delay and reverb times to song tempo. DJs tap along to a track to identify its BPM for beatmatching. Composers and arrangers reference the note duration table to calculate metronome markings and tempo relationships between sections.

BPM Calculator is part of the facilita.tools suite of free browser-based utilities for creative professionals. Available in Portuguese, English, and Spanish, optimized for desktop and mobile browsers.

Frequently Asked Questions

How does tap tempo detection work?
Tap any button or key in rhythm with the beat. The tool measures the time between each tap, averages the intervals, and calculates the BPM. More taps produce a more accurate result.
How do I set delay time to match tempo?
Enter your song's BPM and look at the note duration table. Use the quarter-note millisecond value for standard delays, or eighth-note and dotted values for faster or syncopated effects.
What note subdivisions are shown?
The table shows whole, half, quarter, eighth, sixteenth notes, plus their dotted and triplet variants — all with exact millisecond durations for the given BPM.
