Surco

Surco is a desktop app for DJs that folds the entire track-prep workflow into a single tool. What normally takes four or five separate apps — a converter, Discogs in the browser, a tag editor, a spectrum analyzer and Apple Music — Surco does in one click, in a couple of seconds per track.

Convert • AIFF, WAV, FLAC or MP3, any format to any other • Already in the target format? Copied as-is, instantly • Match volume to a target loudness or peak • Re-export without touching your Traktor cue points

Tag • Fill artist, album, label, BPM and key from Discogs and Bandcamp • Match a whole release automatically by track length • Bulk-edit and find-and-replace with regex • Pull cover art from Discogs or drop in your own

Analyze quality • Draws the audio spectrum and catches fake-lossless MP3s (re-encoded files disguised as lossless) • Colour read-out of LUFS, true peak, dynamics and noise • Detects BPM and key from the audio itself • Warns if a track is already in your Apple Music library

Organize & export • Send to Apple Music with tags and cover art embedded, even for WAV • Export your queue to rekordbox or Traktor • Rename files with {artist} - {title} templates • Import whole folders and preview before converting
