About

Tempo detection that just works.

getlivebpm.com is a small, focused tool: open the page, let it listen, and get the BPM. Built by Mobilefunk — a studio in the Netherlands that makes tools for musicians, coaches, and anyone who cares about timing.

Why we built this

No installs. No uploads. Just the tempo.

01 · Problem

BPM tools are clunky

Standalone tempo apps want you to install something, upload a file, or sign up. Existing web tools guess from taps only, or refuse system audio. We wanted something that opens, listens, and answers.

02 · Solution

Neural net in your browser

A compact TempoCNN model runs locally via TensorFlow.js. Feed it 12 seconds of audio — from your mic or a shared tab — and it predicts the BPM with decimal precision. All inference is client-side.

03 · Vision

Tools for everyone who times

Producers, DJs, dance teachers, drummers, cyclists, running coaches — anyone who cares about tempo should have a fast, free tool. getlivebpm.com is that tool.

What it does

More than a tap counter

Live microphone detection — point any mic at the source, get the tempo.
System-audio capture — analyse anything playing on your machine, no cables.
Tap tempo fallback — no audio? Tap along and get an instant average.
Decimal precision — parabolic interpolation gives sub-integer BPM.
Runs offline once loaded — the model ships in the page, ~5 MB, one-time download.
Free to use — no account, no payment, no ads tracking you.
