Intro and outro edits
Choose the drop, set 8, 16 or 32 bars, and build a clean mix-in or mix-out.
In your browser · nothing to install
Make an intro edit for any track. In a few clicks.
Half your collection never gets played, because those tracks start cold and there is nowhere to mix in. Pick the point where you want the record to drop — CratePrep builds the intro for you, out of the track's own audio, with the vocal lead-in over the top so it flows.

Drop a track in and hear it.
No account, no install. Pick where the record should drop and you will hear the intro built out of the track's own audio, with the vocal walking in over the end of it. Sign up only when you want to keep the file.

The editor
One browser editor.
Every part of the edit.
Drop in your track, choose an edit, and stay in control of the BPM, grid, loop, vocal and final preview.
Acapella and instrumental
Separate the track into parts and decide what carries through each transition.
Shape the loop
Choose where the loop comes from, adjust its length, and audition the join before rendering.
Why you need it
Your record pool never made
an intro for that one.
Pools edit what is current. Intro versions get cut for new releases while they are being pushed, and the back catalogue almost never gets the treatment — so the older records in your crate, the ones that would actually go off, are exactly the ones with no intro version anywhere.
Until now, the only fix was a DAW and an hour a track.
Making one before
- Buy and learn a DAW
- Run the track through stem separation
- Hunt for the first real downbeat by ear
- Copy, paste and tile a section to length
- Nudge the join until the drop sits on the one
- Bounce it, listen back, do it again
Making one now
- Click the track in your crate
- Click where you want the record to drop
- Choose 8, 16 or 32 bars
- Audition the seam
- Save
What it does
You pick the moment.
It does the work.
Everything that made this a studio job is handled for you — the separation, the phrasing, the tiling and the alignment. What is left is the one decision only you can make: where the track should come in.
It does the hard part
Finding the downbeat, pulling the instrumental out, tiling it to length and lining the drop up to the grid — that is the whole job, and it happens on one click. You choose where the track should come in. CratePrep does the rest.
The vocal lead-in comes too
It lays the vocal pick-up over the end of the run-up, so the track walks in instead of appearing. That is the detail that separates a proper intro edit from a track with a loop stuck on the front.
Choose where the loop comes from
The bars at the drop are the usual choice, but if they are too busy, or the vocal will not come off cleanly, there are often better eight bars elsewhere in the record. Audition each one with the vocals already stripped before you build anything.
Star now, edit later
Going through a crate and spotting the tracks that need an intro is a different job from making them. Star them as you find them and the prep list brings the lot back together, across every library.
Your library
Your crates, down the side.
CratePrep opens the crates out of whichever DJ program you already use and shows them nested the way that program does — with artist, title and BPM from the library itself, so you are picking tracks, not filenames.
Serato
Crates and subcrates straight from the Serato library, including Serato 4.
Rekordbox
Opens the Rekordbox database and lists your playlists with their real track counts.
VirtualDJ
Your playlists and browser folders, nested the way VirtualDJ nests them.
Engine DJ
Your Engine library and playlists, with the beatgrids Engine already worked out.
Nothing is ever written back to your library. On Traktor or djay, drag and drop works the same — you just pick the file yourself.
How it works
Three clicks and a listen.
01
Pick the track
Click it in your crate list, or drag the file in. Artist, title and BPM come from your library.
02
Click where it should drop
Find the moment it kicks in on the waveform, set the drop there, and choose 8, 16 or 32 bars. That is the only decision you make.
03
Audition and save
Hear just the join before you commit, then export the edit wherever you like and let your DJ software find it.
