| # 🎛️ SoundForge Studio | |
| **Professional Copyright-Free Audio Processing Suite** | |
| Make any song copyright-free for YouTube, create custom remixes, build multi-track mashups, and separate audio stems — all in one powerful web application. | |
| --- | |
| ## 🚀 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 | |
| Full control over every element: | |
| - Individual stem volume control (Vocals, Drums, Bass, Melody) | |
| - Vocal pitch shifting (±12 semitones) | |
| - BPM/tempo adjustment | |
| - Professional effects: Reverb, Chorus, Delay | |
| - 3-band parametric EQ | |
| ### 🔀 Mashup Creator | |
| Combine up to **6 songs** simultaneously: | |
| - **Layered** — Vocals from Track A + Instrumental from Track B | |
| - **Sequential** — Tracks with smooth crossfades | |
| - **Blend** — All tracks mixed at custom volumes | |
| - **Alternating** — Switches between tracks every 8 seconds | |

| - 🎸 Full Instrumental | |
| ### 📊 Audio Analyzer | |
| Professional audio analysis: | |
| - BPM detection | |
