🚀 Features

🔓 Copyright-Free Processing

Transform any song into a copyright-free version using an 8-step fingerprint modification pipeline:

1. Stem Separation — Splits audio into vocals, drums, bass, and melody
2. Per-Stem Micro-Pitch Shifting — Different subtle shifts per element
3. Micro-Tempo Adjustment — Barely perceptible speed changes
4. EQ Profile Shift — Subtle frequency balance changes per stem
5. Spatial Modification — Reverb and stereo field changes
6. Texture Addition — Envelope-shaped micro-noise layer
7. Micro-Timing Offsets — Sample-level timing shifts between stems
8. Professional Mastering — Normalize, limit, and stereo-widen

🎚️ Remix Engine

• Individual stem volume control (Vocals, Drums, Bass, Melody)
• Vocal pitch shifting (±12 semitones)
