Useful timing math, without interrupting the music.

BeatTiming brings free music timing tools into one place. It is built for DJs, producers, musicians and audio engineers who want a quick answer while they work.

How BeatTiming helps you make music

Why it exists

A small timing question can break the flow of a session. How long is a dotted eighth note? How many seconds do 16 bars last? How much does a tempo change shift the pitch? BeatTiming helps you work out those values in your browser.

Use tap tempo to find the pulse by hand. Turn BPM into note lengths, delay times, reverb timing or LFO rates. Other tools help you plan a DJ set, compare deck tempos, measure a loop or convert sample frames into time.

How calculations are handled

Choose the tool that matches your question. Enter the tempo, time, sample rate or other values it asks for. The answer updates as you work. Each tool shows its formula, a worked example and the limits you should know.

For example, a quarter note at 120 BPM lasts 500 milliseconds. A 16-bar section in 4/4 lasts 32 seconds at that tempo. Those values can help you set a delay or plan a phrase, but listen to the result in the full mix.

Calculation method and accuracy

The tools run on your device. You do not need an account, a microphone or an audio-file upload. Each tool states how it rounds its answer. Tests check known values, input limits and results that can be checked in reverse.

The Version 23 release passed 9,717,735 automated checks across 1,667,709 test cases. These counts describe software tests, not human reviews. Read how we test the calculations.

Designed to stay predictable

The tap surface and core formulas are designed to stay familiar. New tools may be added while existing controls stay consistent for people who return to the site. Open the calculator directory.
