CortexDJ

CortexDJ is desktop DJ software for Windows 10/11 and Apple Silicon Macs (beta). Point it at a folder of your own music and it analyzes every track on your computer (Camelot key, BPM, 1-10 energy, intro, drop and outro), then builds a beatmatched set that follows the Camelot wheel and an energy curve, and renders it to a WAV or FLAC file with a timestamped tracklist.

Simple mode asks three things: what to mix, how long, and which transition length. Advanced mode adds live decks with EQ, filter, effects, loops and hot cues, plus plain-English requests and a loudness target. A set can be played live with any control taken over mid-mix, or exported to rekordbox, Serato, VirtualDJ, Traktor, Engine DJ, Mixxx and djay.

It works offline on local files (MP3, FLAC, WAV, AIFF, M4A/AAC, OGG), reads existing Mixed In Key and Beatport tags, and does not work with streaming services. The free edition covers analysis, auto-mixing, rendering and export for home use; Pro and Lifetime add MIDI controllers, recording and live-streaming, and are required for gigs and other public use.
