Free music production tools for DJs and producers
Most music production tools cost money. Mixed In Key charges $58 for key detection. Chordify charges a monthly subscription for chord analysis. Tunebat requires a paid tier for batch lookups. BeatKey Tools offers the same core functionality, completely free.
The BeatKey suite covers the four most common analysis needs for DJs and producers: knowing the BPM and key of a track (BeatKey), understanding its chord progression (Chord Finder), calculating the right delay times (Delay Calculator), and working out which scales fit a given key (Scale Finder). The Note Frequency Calculator rounds out the suite for producers who work with 808s, synthesizers, and sample tuning.
Every tool runs in your browser using WebAssembly. Audio analysis happens on your device, not a server. This means faster results, complete privacy, and support for files that have never been on any streaming platform. Unreleased music, stems, samples, and DJ edits all work just as well as finished commercial releases.
The tools are designed to work together. After BeatKey gives you a BPM and key, a single click opens the Delay Calculator pre-loaded with your BPM. The Camelot code links directly to the Interactive Camelot Wheel. Scale Finder covers all 18 scale types across every root note, so once you know the key, you can immediately see which notes fit.
