Analyze tracks in Serato DJ.

Analyze Files is the command that makes Serato read each audio file and store what it learns: the waveform overview, a check for problem files, and, if enabled in Analysis Settings, BPM, key, and a beatgrid. Until a file is analyzed, its BPM and key columns stay empty and the overview does not show. Serato also analyzes an unanalyzed track the first time you load it to a deck, but running Analyze Files on a crate or your whole library does it in one pass, before you play. To check one file before it ever reaches Serato DJ, the browser key and BPM finder reads its tempo and key without importing anything.

To analyze files in Serato DJ Pro, open Analysis Settings next to the Analyze Files button above the library. Check Set Key and Analyze BPM / Beatgrid, pick a BPM Range that suits your music, then click Analyze Files or drag tracks, a crate, or a folder onto the button. That is the standard way to analyze music in Serato DJ Pro. Only Serato DJ Pro 3.3.5 or below requires your hardware to be disconnected first.

The workflow is the same as in Pro. To analyze files in Serato DJ Lite, open the software and click the Analyze Files button above the library, or drag single tracks, a crate, or a folder onto it. In Analysis Settings, Analyze Key and Analyze BPM / Beatgrid control what gets written. Analyzed tracks keep their BPM, key, beatgrid, and overview data if you later upgrade to Serato DJ Pro, since both use the same library.

BPM comes out of the same analysis pass. To analyze BPM in Serato on its own, leave Analyze BPM / Beatgrid checked in Analysis Settings, uncheck Set Key, and pick the BPM Range that matches your music. Then run the pass. If you only want to scan BPM in Serato for a few tracks with wrong values, drag them onto Analyze Files to re-analyze them and check the result on a deck. See fix BPM and beatgrid in Serato for the manual fixes.

To analyze TIDAL tracks in Serato, click Analyze Files to bulk-analyze every TIDAL track in your library, or select some and drag them onto the button. Once analyzed, the key, BPM, and full waveform show, and you can add cue points and loops. An unanalyzed streaming track is also analyzed when you load it to a deck. TIDAL in Serato DJ Pro needs a TIDAL DJ subscription and an active internet connection; there is no offline playback.

For pre-session library preparation, yes. Vibes runs BPM and key detection across your whole library in one batch pass and exports the results into Serato crates. Serato still does its own analysis when you load a track into a deck, but if Vibes has already processed the file you can verify and trust those values before you ever open Serato.

Vibes stores analysis data in its own database and writes to Serato via .crate files for organization. It does not directly overwrite BPM or key fields in Serato's internal library database, so your existing Serato analysis is not at risk.

Vibes uses Camelot Wheel notation (e.g. 8A, 8B) via its Skey neural-net detector. Serato's Show Key As option, under Setup > Library + Display, chooses the notation shown in its Key column. If you keep Serato on musical notation, you can cross-reference the two: 8A in Camelot corresponds to A minor, for example. Vibes also shows the Camelot neighbors of any track with its Find Compatible feature, which speeds up harmonic mixing prep before your set.
