Analysis

Every track, heard properly.

Waveform
Three bands, one glance.
Lows, mids, and highs each get their own colour, so the breakdown and the drop are visible before you press play. Prefer RGB waveforms? They are one setting away.
BPM and beatgrid
Locked to the downbeat.
Ora DJ finds the tempo and the first downbeat, then lays a grid that your cues and loops snap to.
Key
Industry-leading key detection.
Built from the ground up for house, techno, and the rest of electronic music, and trained on the minor keys this music lives in. You get the Camelot code to mix with.
Energy
Energy from 1 to 10, bar by bar.
One score to sort a crate from warm-up to peak, and a curve that shows where the track builds and where it breathes.
Vocals
See where the vocals sit.
Every passage with vocals is marked on the waveform, and the track gets a vocal percentage. Filter by it, sort by it, or use it in a dynamic playlist, so two vocals never collide by accident.

Save as dynamic playlist

Dynamic playlists

A little more specific than house.

Keep every techno track, or only house tracks rated four stars and up. Group AND and OR rules to make a playlist that follows your taste as the library grows.

Ora DJ dynamic playlist editor: Genre is Techno OR a group where Genre is House AND Rating is at least 4 — Techno OR (House AND a rating of at least 4). Example tracks.

Example tags. Try your own selection.

File organization, if you want it

New music, filed the way you would.

Ora DJ can rename new files from their tags and move them into a folder tree you choose. Let it happen on arrival, or collect new tracks in an inbox and fix their tags first. Leave it off and your files stay exactly where they are.

Organize files on import

Off by default. Tracks already in your library keep their names and folders.

Fix the tags first, then import when you are ready.

Tag edits you make in Ora DJ can also be written back to your MP3, FLAC, AIFF, WAV, and M4A files. That is optional too.

Library health

Nothing gets lost.

Years of collecting leave moved files and duplicate copies behind. Ora DJ finds moved tracks by their audio, not their path, cleans up duplicates, and backs up its library every day.

Auto relocate

Moved or renamed files on disk? Ora DJ recognizes each track by an audio fingerprint, finds it again, and relinks it with its cues, tags, and playlists intact.

Duplicate detection

Find exact and near-duplicate copies, see which one to keep and why, then merge play counts, tags, and ratings into the survivor and archive the rest. Playlists never break, and every step is reversible.
