Full demo
Extend an intro for mixing
A screen recording of the edytlab desktop app: a DJ asks Claude for a track's tempo and bar length, then has its first 8 bars copied to make a 16-bar intro, and exports a WAV.
1:55, 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 asks for Solar Flare's tempo and bar length without changing anything: 124 BPM, a 1.935-second bar, the first downbeat at 0.476 s. The drums-only first 8 bars are copied from that downbeat and pasted after themselves, so the intro runs 16 bars and the track grows from 32 to 47.5 seconds. A 200 Hz high-pass holds the low end back until the drop at 31.45 s, and Claude suggests 120–150 Hz if the intro sounds too thin. The first 4 bars fade in and the track is exported as a WAV; Claude flags that it peaks at −0.0003 dBFS, right at full scale. You hear the new intro, then the drop at 0:31. Waits for Claude are sped up; every playback is in real time, with sound.
