DJ Mix Mode
Optional workspaceThis is a deliberately secondary workspace — it never appears on Home or in the standard project flow. Build a multi-track set from separate imported files, each analyzed for tempo and key, sequenced with real crossfade transitions and optional tempo matching.
Every transition in the list is real signal processing (filters, EQ bands, delay/feedback, a diffuse reverb network, playback-rate automation, synthesized noise, reversed buffers, gain gating, or buffer grains), rendered sample-accurately via OfflineAudioContext — nothing here is a relabeled crossfade. “✨ Auto (best fit)” — available per-boundary, as the default for new tracks, and via “Auto-Assign Transitions” for the whole set — picks from each pair’s actual tempo and key compatibility and won’t repeat the same move twice in a row. “Match tempo” and “Tempo Ramp” both change playback speed to align BPMs — like a turntable pitch fader, pitch shifts along with tempo, so it’s honest about the trade-off rather than silently pretending to time-stretch; Tempo Ramp eases into the match gradually instead of snapping instantly. The waveform above is colored by real spectral centroid per segment (bass=warm, mids=green, highs=blue) — not decorative, it’s derived from the actual audio.
