How it works

  1. 01

    Pick the folder

    Choose your crate folder on disk. Nothing is uploaded — the browser reads MP3, WAV, FLAC, AIFF, M4A and OGG straight from the file.

  2. 02

    Full analysis

    BPM, Camelot (average and fractional), energy, vocal %, beat grid and cue points — all on-device.

  3. 03

    Ready to play

    Harmonic pairs, stems to audition the transition, Rekordbox XML, M3U and TBPM/TKEY tags on the MP3.

Who it's for

  • You prep sets in Rekordbox and want Camelot + energy without paying for Mixed In Key
  • You don't want to upload your library to any cloud
  • You want to hear stems (mute the vocal, isolate the kick) while building the transition
  • You work on a laptop or tablet and don't want yet another desktop app

Not for you if

  • You need studio-grade neural stems like Demucs or Lalal.ai
  • You want to identify unknown tracks like Shazam
  • You plan to mix the whole show inside Beat.Tools in the booth — today it's prep + preview, not a CDJ replacement

Harmonic mixing

Camelot wheel with compatible pairs. Energy and fractional key for clean transitions — no second tool.

Stems while you prep

Each stem has its own waveform. Mute the vocal, isolate the kick, click to seek. Separation runs on-device.

Honest: stems are on-device HPSS separation — great for auditioning vocal and kick while prepping, not studio-grade stems.

Out to Rekordbox

Analyze here → write BPM and key into the MP3 → export XML → open Rekordbox with key and energy already in the crate.

Also exports M3U and CSV playlists. It doesn't replace Rekordbox in the booth — it preps the crate for it.

Privacy in 3 lines

  • The WAV/MP3 stays on your disk. Analysis runs in the browser.
  • Identification reads tags and filenames — no audio fingerprint is sent.
  • Offline mode uploads nothing. With an account, your crate and analyzed files live in your cloud storage, to open on another device.

About offline mode

  • Once plans launch, offline mode stops working on Freemium and becomes available from the Starter plan up.
  • Offline mode requires an internet connection at least once a month to confirm your subscription is still active.
  • In offline mode you can analyze as many tracks as you want with local-only storage on your machine — nothing uploads to the cloud.
  • Outside offline mode, every analysis uploads the track to your cloud storage, with per-user tracking and bucket/folder organization.

Frequently asked questions

Do I need an account to analyze?

No. In offline mode you can analyze tracks without logging in, right in the browser. The account saves your crate, sets and files so you can open them on another device.

Which browsers work?

Chrome and Edge give the best experience (direct folder access). On other browsers you pick files manually.

Does it replace Mixed In Key?

For crate prep — BPM, Camelot, energy and Rekordbox export — yes, in the browser and free while in preview. We don't do offline batch queues of thousands of tracks (yet).

Are the stems neural?

No. They're on-device HPSS separation: great for auditioning vocal/kick while building a transition, not for producing remixes.

Does my audio upload anywhere?

Analysis never needs an upload: it runs on your device. In offline mode, your audio stays on your computer. With an account, analyzed files go to your private cloud storage so you can open the crate on another device.

Does it work on mobile?

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

How much does it cost?

Free while in preview, with unlimited local analysis. If anything becomes paid later it will be account features (sync, batch export) — local analysis stays on your device.
