    Recurring patterns

    • Recurring low-end clash

      Two basslines fighting in the sub kills club translation and creates phase mush. Detected 2× (6:52, 29:42).

    • Repeated volume jumps

      Gain-staging mismatches break perceived continuity and force the crowd to readjust. Detected 2× (6:52, 29:42).

    • Long static loops (6×)

      Sections sitting on the same loop without layering, EQ moves or tension shifts (48:00, 54:00, 72:00, 80:00, 108:00, 112:00). Long loops kill dancefloor momentum.
