Convert audio files without losing your Serato cues.

Formats

Whatever is in your library goes in, a format your gear plays comes out

Pick tracks by format on the Convert page, search and untick the ones to leave alone, or select tracks in your crates, right-click and choose Convert. Crate Cleaner flags the formats that cause trouble before you start: WMA, which Serato on Mac cannot play, Opus, which Serato cannot play at all, and FLAC, which older CDJs cannot read.

Serato

Cue points, loops and beatgrids come with the file

A plain audio converter writes a new file and leaves behind everything Serato stored in the old one. Crate Cleaner copies it across. When the new file is an MP3, AIFF or WAV, the hot cues, cue colours, loops, beatgrid and Serato’s analysis go with it, from MP3, AIFF and WAV files and also from M4A and FLAC files Serato has tagged.

• Tags and artwork: title, artist, album, album artist, genre, year, track number, BPM, key, comment, composer, grouping and label
• Cues land on the same beat: encoder delay is removed when decoding, so cue times still point at the same audio
• Star ratings carried between MP3, AIFF and WAV files
• Gaps filled from Serato 4: a field the file is missing but Serato’s library knows is written into the new file

FLAC, Apple Lossless and AAC outputs keep the tags and artwork but not Serato’s cues. The preview tells you how many of your files would lose cues before anything runs, so you can pick an AIFF or MP3 preset instead.

Quality

No fake 320s, and no quality the source never had

Turning a 128 kbps file into a 320 kbps MP3 makes a bigger file that sounds the same, which is exactly the fake that Audio Quality exists to catch. Crate Cleaner will not make one.

Review

Nothing in your library changes until you press Replace

New files are written next to the originals, which are never touched. Each converted track waits in a review list showing the old and new format, how many cues were kept, any notes, and the new file size. Discard deletes the converted copy. Replace swaps it in.

• The original moves to the Archive, where you can restore it
• Play counts and history stay: the same track in your library points at the new file
• Serato crates follow: every crate that listed the old file is pointed at the new one
• Serato DJ Pro 4 tidied up: after you open and quit Serato once, its old entry is folded into the new file with plays kept, after a backup

How it works

Pick the tracks, pick a format, check the result

1. Pick the tracksChoose formats on the Convert page and untick what to leave out, or right-click a selection in your crates and choose Convert.
2. Pick a formatChoose one of nine presets. The preview counts what will convert, what is skipped, what is capped and where cues are kept.
3. Review, then ReplaceCheck the converted files, discard any you do not want, and press Replace. Quit Serato first so it does not undo the crate changes.
