Free Online Tempo Detector & BPM Tap Calculator

Our tempo detector and BPM tap calculator is the fastest way to measure the beats per minute of any song, rhythm, or groove. Tap the large button — or press the Spacebar — to the beat, and the tool instantly calculates your BPM using the average interval between taps.

How to Measure BPM

Using the Online Metronome

After measuring your tap tempo, click Match Tap to sync the metronome to your detected BPM. The four light indicators will flash in 4/4 time. Click Start and the metronome will produce audible clicks using the Web Audio API — no external plugin needed.

Comprehensive Guide: How to Find, Measure, and Calculate Song BPM

Whether you need an accurate bpm measure, an intuitive bpm converter, or a reliable beats per minute finder, this tempo checker online provides professional rhythm analysis directly in your browser. Unlike downloading a bulky bpm finder app or tap metronome app, you can instantly tap tap tempo or run a quick tempo tap online session on any mobile or desktop browser without installation.

How to Count Beats Per Minute Accurately

To count beats per minute for any live track or DJ set, simply tap along to the quarter-note beat with your spacebar or mouse for at least 4 to 8 consecutive beats. Our running moving-average algorithm filters out outlier intervals, giving you a smooth, rock-solid BPM reading.

Acoustic Timing: Converting Hz to Milliseconds and Delay Times

Audio engineers and music producers frequently need to convert frequency in hz to milliseconds and tempo intervals to dial in compressor release times, digital delay repeats, and LFO modulation cycles. At 120 BPM, a quarter note lasts exactly 500 ms (2.0 Hz), while an eighth note corresponds to 250 ms.

Frequently Asked Questions

After 4 taps, accuracy reaches ±2 BPM. After 8 taps, ±0.5 BPM. The tool uses high-resolution timestamps (performance.now()) for sub-millisecond precision, far more accurate than stopwatch-based approaches.
Automatic audio analysis requires microphone access and FFT signal processing, which is available in our paid API plan. This tap-based tool is the manual approach — tap along to any song in real time.
Some songs can be counted at twice the natural tempo (e.g. tapping on every 8th note instead of every quarter note). The Half BPM button divides your current reading by 2 to correct for this.
Yes! Once the page loads, the metronome uses the Web Audio API — a built-in browser feature — to generate click sounds. No network calls are made during metronome playback.
Tap to tempo (also called "tap tempo") is a technique used by DJs, producers, and musicians to manually synchronize equipment to a song's rhythm. You tap in time with the beat, and the tool calculates the resulting BPM.
