Marco V.

Club DJ, Berlin · 12 years

Terrified it would mess up my Rekordbox cues. It didn't touch a thing.

Sarah K.

Mobile DJ, London · 800+ gigs

Had 128kbps copies mixed in with 320s and never knew. That's a live set disaster waiting to happen.

Questions & Answers

Does it modify my Serato/Rekordbox/Traktor data?

No. Strictly read-only. Never writes to audio files or touches cue points, beat grids, loops, or any DJ metadata.

How does it detect duplicates?

By listening to the actual audio - like Shazam. Two files that sound the same match, regardless of name, bitrate, or format.

Will it delete files automatically?

No. You review every group and decide. Nothing moves without your action.

What does 'quality scoring' mean?

Each file scored by bitrate, format, and encoding quality. You instantly see which copy sounds best.

Does it need internet?

No. Everything runs locally. No cloud, no uploads, no accounts.

External drives and NAS?

Yes. Any drive your computer can see - USB, external, NAS, SD cards.
