Full demo
A three-track mini-mix
A screen recording of the edytlab desktop app: a DJ has Claude bring three tracks to 124 BPM, join them with overlapping crossfades, match their loudness and export the mix as a WAV.
1:58, played in real time with the app's own sound, and no voice-over. Nothing plays until you press play.
What it shows
A DJ builds a warm-up mix at 124 BPM. Midnight Drive and Neon Rush are time-stretched to 124, keeping their pitch, and Claude checks that their beats now line up with Solar Flare's. Each track comes in about 4 bars before the one before it ends, with a straight-line crossfade over each overlap; Claude brings Neon Rush in on Solar Flare's bar line rather than at the exact 4-bar mark, which makes that overlap 8.77 s. Each track is brought to about −14 LUFS, with a limiter at −1 dB on the master, and Claude notes that the fades were counted in the measurement. You hear both transitions, then the mix is exported as a 79-second WAV. Waits for Claude are sped up; every playback is in real time, with sound.
What happens, in order
There is no voice-over. Each line is a moment in the video, from the second it starts.
