Short
Music Library Doctor is a Mac & Windows app that repairs DJ and music libraries — it finds duplicates by listening to the audio itself, exposes fake "320 kbps" MP3s and fake FLACs with spectrum evidence, fixes broken track paths, and converts playlists between Rekordbox, Serato and VirtualDJ. All analysis runs locally; Pro is a one-time lifetime license.
Long
Music Library Doctor (MLD) is a desktop application for DJs and music collectors whose libraries have grown messy over years of downloads, re-imports and drive migrations. It reads Rekordbox, Serato DJ and VirtualDJ libraries natively — and plain folders for users without DJ software — then finds what's actually wrong: duplicate tracks hiding in different formats and bitrates (matched acoustically, not by filename), files claiming "320 kbps" or lossless quality that were transcoded from worse sources (proven with a per-track frequency-spectrum chart), and playlist entries pointing at moved or missing files.
Repairs are just as concrete: broken paths are fixed in bulk, playlists are re-pointed before any duplicate is removed, deleted files go to a recoverable trash (including on NAS drives), and playlists convert between DJ apps with folder hierarchy preserved. Everything runs locally on the user's machine — no cloud uploads. The scan tier is free; Pro is a one-time lifetime license. MLD was built by Koray Onur, a DJ who needed it for his own decades-deep DJ collection.
Music Library Doctor started the way most useful tools do: with a problem its maker couldn't stop running into. Koray Onur is a DJ and a software engineer, and like every working DJ his library had quietly rotted over the years — the same track bought twice in different formats, "320 kbps" files that turned out to be upscaled junk, playlist entries pointing at folders that had moved three drives ago. None of it shows up until the worst possible moment: a track greying out mid-set, or a thin, brittle sound on a big club system that was fine in headphones.
The existing options each solved one slice. Spek could show you a single file's spectrum, one at a time. Other checkers gave a verdict but couldn't fix anything, dedupe a library, or repair a broken path. Nothing did the detection and the repair in one place, across the DJ apps people actually use. So Koray built the thing he wanted for his own crates — and it turned out thousands of DJs and collectors had exactly the same mess.
"A clean library isn't glamorous. It's just the reason the night doesn't fall apart. I wanted a tool that treats your files like they're yours — everything runs on your own machine, nothing gets uploaded, and it shows you the evidence for every call it makes instead of asking you to trust a score."
That principle — local-first, evidence-first — is why the fake-file detector draws the actual frequency spectrum for every track, why duplicates are matched by listening to the audio rather than trusting filenames, and why playlists get re-pointed to the copy you're keeping before anything is ever moved to trash. It's a repair kit, not a black box.

Try it yourself: the free in-browser checker draws the frequency spectrum for any file you drop in and flags fake-320s — screenshot the verdict for your article, and point readers to it too. Nothing is uploaded.
