DJ Mixing Engine

The mixer uses professional techniques:

• LUFS loudness normalization (EBU R128)
• High-pass filtering (40Hz rumble removal)
• Beat-aligned time-stretching
• EQ-based crossfade (bass swap transition)
• Equal-power S-curve crossfade
• Final mastering to -14 LUFS (streaming standard)
