DJ tools
Small, focused tools for planning sets. Each one runs entirely in your browser — drop in a crate export, or the audio itself, and it is parsed on your own machine, never uploaded.
-
Key route finder
Plot a path around the Camelot wheel from the track you're playing to the one you want to reach, then pull bridge tracks out of your own crate for every step along the way.
-
Set sequencer
Pick the tracks you want to play and get an order that keeps the keys moving smoothly and the tempo sensible. Every transition is graded, so you can see which ones still need work.
-
Crate health check
Audit your library for untagged keys, missing tempos, duplicates, mixed key notation and files that are quietly lower quality than the rest.
-
Track check
Read a file's spectrum to find what it really is, not what the tag claims, and measure its loudness in LUFS. Catches upscaled rips pretending to be 320.
-
Audio converter
Turn a folder of AIFFs into FLACs that fit on a USB stick, or flatten anything back to plain WAV. Lossless both ways, decoded and re-encoded in the page.
-
Pitch & key calculator
How far you have to pitch a track to reach a tempo, what that does to its key, and whether it's still inside a deck's range. Nothing to load.
-
Playlist converter
Turn a rekordbox export into a spreadsheet, an M3U8, JSON for a script, or back into rekordbox XML — rewriting keys between notations on the way through.
