BEAT FINDER
Overview
Our online Beat Finder is a free browser-based tool that detects the tempo (BPM) and rhythmic feel of any audio file. DJs, producers, dancers, choreographers and editors use the beat finder to align cuts, build mashups, line up samples and pick tracks at the right BPM.
Privacy First
All analysis runs locally in your browser. The beat finder never sends your audio to a server, so demos, stems, mixes and unreleased tracks stay completely private on your device.
Performance
Powered by a multi-feature onset & beat-tracking engine, the beat finder returns a precise BPM, plus key, energy and danceability as bonus context — all in seconds.
The beat finder reports the song's overall BPM with the precision DJs and producers rely on for grid alignment, beat matching, sync mixing and choreography.
On top of the beat, the tool also returns the musical key, scale and Camelot Wheel code — so harmonic mixing and mashups are just as fast as beat matching.
No installs, no signup, no cloud uploads. Drag a file into the page and the beat finder runs locally on desktop, laptop or any modern mobile browser.
A beat finder is an audio analysis tool that detects the tempo (BPM) of a song — how many beats happen per minute. DJs, producers, dancers and editors use a beat finder to match tracks, sync cuts to music and build mashups.
Yes. The beat finder is 100% free with no signup, no quota and no hidden fees. Analyze as many songs as you want, whenever you want.
No. The entire beat finder runs inside your browser. Open the page, drop in an audio file, and the BPM is detected automatically.
No. The beat finder processes audio locally on your device. Your files never leave your browser, which keeps your demos and unreleased work private.
Any format your browser can decode — MP3, WAV, FLAC, OGG, AAC and M4A. Most modern browsers cover all of these out of the box.
The beat finder uses a professional rhythm analysis engine with multiple onset-detection functions. It is highly accurate for genres with a clear rhythmic structure — pop, EDM, hip hop, rock, lo-fi, drum & bass — and works well even on noisier mixes.
Some songs have ambiguous tempos that can be heard as 80 or 160 BPM, for example. If the result feels off by half or double, just use the harmonic version that fits your set or your edit — the beat finder is reporting a valid analysis either way.
The same engine that finds the beat also detects the musical key, scale and Camelot Wheel code for free. You get harmonic-mixing info as a bonus — perfect for DJs and mashup makers.
Most songs maintain a consistent tempo, so analyzing the first 60 seconds gives a fast, accurate result while keeping the tool responsive — even on mobile browsers.
Absolutely. Knowing the exact BPM lets you sync cuts, transitions, dance moves and lighting cues to the beat — and pick songs at the right tempo for your routine.
Drop in your first track and the beat finder will reveal the BPM, key and Camelot code in seconds.
