Why this click doesn’t drift

Naive metronomes fire setTimeout for every tick, so the click wobbles whenever the browser is busy. This one uses a lookahead scheduler: a light timer wakes every 25 ms and books each click ~100 ms ahead on the Web Audio clock, which is sample-accurate. The result is a rock-steady pulse from 30 to 260 BPM, even with subdivisions running.

About Metronome

Metronome is a free, private tool by Digital Heroes that runs entirely in your web browser. It gives you a sample-accurate click powered by the Web Audio API, so the pulse never drifts, even at fast tempos or with subdivisions active. Choose your time signature (2/4, 3/4, 4/4, or 6/8), pick quarter, eighth, triplet, or 16th-note subdivisions, toggle the accent on beat 1, and adjust volume. No sign-up, no installation, and it keeps working offline once the page has loaded.

What you can do

Set an exact BPM from 30 to 260 using the slider or the number input.

Tap tempo: tap the button in rhythm and the metronome calculates your BPM from the last four intervals.

Choose a time signature: 2/4, 3/4, 4/4, or 6/8, with a visual beat-dot indicator for each bar.

Add subdivisions: click down to eighth notes, triplets, or 16th notes at any tempo.

Export a WAV click track (4 to 64 bars) with your current tempo, signature, subdivision, and accent baked in, ready to drop into any DAW.

Watch the pendulum swing in sync, or toggle it off for a minimal view.

How to use Metronome

Open Metronome in your browser. No signup or install needed.

Set your BPM with the slider or type an exact value. Or tap the Tap Tempo button in rhythm to detect your tempo automatically.

Choose a time signature and a subdivision from the buttons below the transport.

Press Start (or hit Space) to begin. The beat dots and pendulum follow the click in real time.

When you need a guide track for recording, set the bar length in the Export panel and click Download WAV.

Frequently asked questions

Is Metronome free?

Yes. Metronome is completely free for everyone. No sign-up, no account, and no usage limits.

Is it private? Does it upload anything?

Nothing is uploaded. The click is synthesized directly in your browser using the Web Audio API. Your practice session stays entirely on your device.

Does it work offline?

Yes. Once the page has loaded, the metronome keeps working with no internet connection. You can also install it as a browser app for quick access.

Do I need to install anything or create an account?

No. Open the page and start playing. The optional "install as app" shortcut just adds an icon to your home screen or taskbar.

Why does the click stay in time even with subdivisions?

The tool uses a lookahead scheduler instead of a plain setTimeout. Every 25 ms a light timer books the next few clicks roughly 100 ms ahead on the Web Audio clock, which is sample-accurate. The result is a rock-steady pulse from 30 to 260 BPM, even in background tabs.

What WAV file does the export produce?

The export renders a 16-bit, 44.1 kHz mono WAV with your current BPM, time signature, subdivision, and accent settings. Choose 4, 8, 16, 32, or 64 bars. The file is named automatically and downloads instantly with no server involved.
