Works with Rekordbox 6 and 7 · macOS (Apple Silicon + Intel) · Windows 10+
Free - no account needed. Includes 1 playlist conversion + full Health Check scan.
The Problem
Missing files with no easy way to fix them in bulk. FLACs that won't play on older CDJs. Duplicate tracks scattered across playlists. Tracks you imported and forgot. Rekordbox doesn't give you the tools to deal with any of it.
Mirrorbox connects directly to your Rekordbox library and gives it the tools it should have had. Convert for CDJs, find and fix missing files, clean up duplicates, collect your library. Changes write back to Rekordbox automatically - open it and everything is already there.
How it works
Mirrorbox finds your Rekordbox library automatically. No exports, no setup. Just open it.
Convert lossless tracks for CDJs, scan for missing files, clean up duplicates, or collect your entire library to one place.
Changes write back to Rekordbox directly. Open Rekordbox and everything is already there. No imports needed.
Formats
Mirrorbox reads every format Rekordbox supports. Lossless tracks are converted. MP3s pass through as-is. The mirrored playlist works on anything.
Features
FLAC, ALAC, and M4A converted to MP3, WAV or AIFF. Playlists rebuilt exactly as they were - same structure, same order, same metadata. Making them older CDJ compatible. Learn more
Three tools in one. Missing files: scan your entire library, locate files manually or auto-scan a folder to fix them in bulk. Duplicates: find tracks that appear more than once, see which playlists they belong to, remove what you don't need. Unsorted tracks: find tracks sitting in your collection but not in any playlist. Full undo on everything.
Copy your entire library - or specific playlists - to a single folder. Everything in one place, organized the way you want it.
No XML exports. No imports. Mirrorbox reads and writes directly to your Rekordbox library. Open Rekordbox and your changes are already there.
About
Mirrorbox exists because I had the same problem. Large FLAC library in Rekordbox, CDJs at the venues, hours wasted the night before every gig converting files and rebuilding playlists manually. I built Mirrorbox to solve it for myself, and figured other DJs had the same headache.
