How to sort a DJ library by key and BPM

Tags differ from one DJ program to the next. A file name is read by every one of them, and by every folder, phone and USB stick too.

Why the file name

Key and BPM tags are written differently by different programs, and some of them get lost on the way to a USB stick, a laptop in a booth or a backup. The file name never does. 04 Undertow [8A 122].wav says what it is everywhere.

One drop for the whole crate

  1. Drop the folder on DropWave, on a Mac or a Windows PC. Every file lands in one table: name, Camelot code, key, BPM, loudness, true peak and length, up to 500 files a drop.
  2. Check the doubtful ones. Listen to anything with a Medium or Low key confidence. A drum tool or a one-chord loop has no key worth writing down.
  3. Check the tempos. Sort by BPM: a 64 in a folder of 128s is a half-time reading, one click away from right.
  4. Tag the names. DropWave writes the Camelot code and BPM into the file names, shows you every change before it makes it, never overwrites a file, and undoes it all with one command.

A catalogue too

The same table exports as a CSV file, for a spreadsheet of your whole library or a list to send to a promoter.

Keep it up to date

DropWave remembers your list between launches and follows files that move. New music: drop the new folder and tag only that.
