Full demo
Beatmatch and blend two tracks
A screen recording of the edytlab desktop app: a DJ has Claude match one track's tempo to another's, blend the two with a crossfade and a low-pass, master the mix and export a WAV.
2:45, 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 what they are working with: both tracks are in F major, and Neon Rush is about 6.7% faster. Neon Rush is time-stretched to Midnight Drive's 120 BPM, keeping its pitch, and started at 16 s, under Midnight Drive's last 8 bars; Claude points out that its bars then run a beat behind and offers to start it at 15.5 s instead. Midnight Drive fades out under a 1 kHz low-pass while Neon Rush fades in. For the master, Claude mixes the two to a new track, compresses it, limits at −1 dB and raises it to about −14 LUFS, then exports a 50-second WAV at −13.9 LUFS, peaking at −1 dBFS. Waits for Claude are sped up; every playback is in real time, with sound.
