Read your crate
the way a DJ does
Selectah measures the tempo, key, energy and genre of every file in a folder, shows you which tracks mix together, and lays out exactly how it would sort them — before it touches a single file.
It reads the record, not the filename
When a file already carries a tempo and key from Rekordbox, Serato or Mixed In Key, Selectah believes them. When it does not, it listens to the audio and works them out.
What goes into what
Pick a track and Selectah ranks the rest of the crate against it, on the wheel and on tempo, and tells you why each one works: same key, wheel neighbour, relative major, the energy boost. Click any of them to hear it.
The whole wheel, at a glance
Every key in your crate, sized by how much of it you have. Tap a segment to keep only those records. The tempo histogram and the genre families narrow the same way.
Nothing is written until you say so
Eleven ways to lay out a crate — by genre, tempo, key, energy, year, artist. Each shows the folders it would make and what would land in them.
See the plan before it happens
The preview is the whole arrangement, folder by folder, down to the last track. Close it and nothing has changed on disk.
Sets that actually chain
Selectah walks the crate looking for runs where each record leads into the next, showing the tempo and key move at every step. Anything that will not chain is set aside rather than buried mid-set.
It will not lose your music
Four things Selectah guarantees, whatever you ask it to do.
Every file stays where it is
The default arrangement makes links. They take no disk space and move nothing. Copy and move are there when you want them.
Including the moves
Every run is written down. One button puts the files back where they were and removes the folders it made.
It renames instead
When two tracks would land on the same name, Selectah renames rather than replace. Nothing is deleted, ever.
Stays on your Mac
No account, no upload, no analytics, no licence server. Selectah makes no outbound network connection at all.
What it needs, and what it reads
- Mac
- Apple Silicon (M1 or later), macOS 12 Monterey or newer.
- Formats
- mp3, m4a, aac, alac, wav, aiff and flac — everything CoreAudio reads.
- Tags it trusts
- Tempo and key written by Rekordbox, Serato, Mixed In Key, Traktor or Beatport are used as they are, which makes a re-scan of a tagged crate take seconds.
- Exports
- Folders of links, copies or moved files, with an .m3u8 playlist per folder carrying the tempo and key of each track.
- Privacy
- Nothing leaves the machine. Read the policy.
