Frequently asked questions

A crate-prep tool for DJs that runs in the browser. It detects BPM, Camelot key, energy, vocal presence, beat grid and cue points, splits stems to audition transitions, and exports to Rekordbox (XML, M3U, CSV and TBPM/TKEY tags in the MP3).

No. Beat.Tools is a DJ track analyzer and has nothing to do with the Ableton Live instrument pack, nor with Ableton, AlphaTheta or Pioneer DJ.

Free while in preview. The announced plans (Freemium, Starter, Pro and Expert) differ in cloud storage, analysis limits and offline mode — details are on the home page.

No. It opens in the browser. If you like, install it as an app (PWA) from the Chrome or Edge menu so it opens in its own window.

Chrome and Edge on desktop: they let you open the whole crate folder at once. On Safari and Firefox you pick files manually.

It works on modern phones and tablets, but crate prep shines on a laptop with direct folder access.

Average BPM and beat grid, Camelot key (average and fractional across the track), energy from 1 to 10, vocal percentage and suggested cue points.

MP3, WAV, FLAC, AIFF, M4A and OGG. TBPM/TKEY tag writing is MP3-only; for other formats the values travel via the XML.

Keys come out as an average and a fractional value, which helps when a track modulates. As with any automatic detection, spot-check the critical tracks of your set by ear.

Yes. Point it at the crate folder and the queue processes tracks in sequence. Speed depends on your computer, because processing is local.

Only to load the app. The analysis itself runs on your device. When online, Beat.Tools can also look up metadata on MusicBrainz and iTunes by the track's name and tags.

No. Identification uses ID3 tags and the filename. No audio fingerprint is ever sent.

Yes. The XML follows Rekordbox's import format: collection, playlists and cues as POSITION_MARK.

Export the XML from Beat.Tools, open Rekordbox under Preferences → Advanced → rekordbox xml, point it at the file and drag the playlists from the XML panel into your collection.

Not necessarily. Once TBPM/TKEY are written into the MP3s, Rekordbox reads the values from the tags when you reload the track info.

There's no export in their native formats. M3U playlists and TBPM/TKEY tags in the MP3 are read by most DJ software.

No. It preps the crate for Rekordbox; it isn't software for playing the show in the booth.

No. They're HPSS (harmonic/percussive) separation done on your device: great for muting the vocal or isolating the kick while building a transition, not for studio-quality remix stems.

The Camelot wheel highlights compatible keys (same number, ±1, relative major/minor and energy boosts) and suggests pairs from your crate, taking BPM and energy into account.

Not today. In offline mode you analyze without logging in. The account saves your crate and opens your library on another device.

Analysis never needs an upload: it runs on your device. In offline mode, the audio stays on your computer. With an account, the files you analyze are stored in your account's private cloud storage so you can play and re-analyze the crate on another device.

Your login email, your crate metadata (tracks, analysis results, playlists and sets) and, while you're signed in, the audio files you've analyzed.

No. When you ask for AI organization or suggestions, only compact track data goes to the model, such as artist, title, BPM, key, energy and genre.

You're responsible for the files you use: only analyze and store music you have the right to use (bought, licensed, produced by you or authorized). Beat.Tools never shares your files with anyone. Details in the terms of use.

There are two separate options in Settings. “Clear data on this device” wipes only this browser's library and cache; the account stays. “Delete account” permanently removes the account, the synced crate and the cloud files, after an explicit confirmation.
