| # 🎵 AI Cover Song Platform | |
| Transform any song with AI voice synthesis! Upload a song, choose a voice model, and generate high-quality AI covers. | |
| ## ✨ Features | |
| - 🎵 **Audio Separation**: Automatically separate vocals and instrumentals using Demucs/Spleeter | |
| - 🎤 **Voice Cloning**: Convert vocals to different artist styles (Drake, Ariana Grande, The Weeknd, etc.) | |
| - 🎧 **High-Quality Output**: Generate professional-quality AI covers | |
| - 🎙️ **Custom Voice Training**: Train your own voice models with personal recordings | |
| - ⚙️ **Advanced Controls**: Pitch shifting, voice strength, auto-tune, and format options | |
| ## 🚀 How It Works | |
| 1. **Upload Your Song** - Support for MP3, WAV, FLAC files | |
| 2. **Choose Voice Model** - Select from pre-trained artist voices or train your own | |
| 3. **Adjust Settings** - Fine-tune pitch, voice strength, and audio effects | |
| 4. **Generate Cover** - AI processes and creates your cover song | |

| ## 📋 Installation | |
| ### For Hugging Face Spaces | |
| This app is designed to run on Hugging Face Spaces. Simply: | |
| 1. Create a new Space on Hugging Face | |
| 2. Upload all files from this repository | |
| 3. The app will automatically install dependencies and launch | |
| ### For Local Development | |
| ```bash | |
| # Clone the repository | |
| git clone <your-repo-url> | |
| cd ai-cover-platform | |
| # Install dependencies | |
| pip install -r requirements.txt | |
| # Run the application | |
| python app.py | |
| ``` | |
| ## 🎯 Usage | |
| ### Basic Usage | |
| 1. Upload an audio file (MP3, WAV, or FLAC) | |
| 2. Select a voice model from the dropdown | |
| 3. Adjust settings if needed | |
| 4. Click "Generate AI Cover" | |
| 5. Download your AI-generated cover! | |
| ### Custom Voice Training | |
| 1. Click on "Train Custom Voice" accordion | |
| 2. Upload 2-5 voice samples (30 seconds each) | |
| 3. Click "Train Custom Voice" | |
| 4. Use the custom model for your covers | |
| ### Advanced Settings | |
| - **Pitch Shift**: Adjust vocal pitch (-12 to +12 semitones) | |
| - **Voice Strength**: Control how strong the AI voice effect is (0-100%) | |
| - **Auto-tune**: Apply automatic pitch correction | |
| - **Output Format**: Choose between WAV, MP3, or FLAC | |
| ## 🎨 Voice Models | |
| ### Pre-trained Models | |
| - **Drake Style**: Hip-hop/R&B vocals with deep, smooth tone | |
| - **Ariana Style**: Pop vocals with high range and vibrato | |
| - **The Weeknd Style**: Alternative R&B with atmospheric vocals | |
| - **Taylor Swift Style**: Pop-country vocals with clear articulation | |
| ### Custom Models | |
| Train your own voice model by uploading voice samples. The system will: | |
| - Extract vocal characteristics | |
| - Train a personalized voice model | |
| - Make it available for future covers | |
| ## ⚙️ Configuration | |
| ### Environment Variables | |
| Create a `.env` file for configuration: | |
| ```env | |
| # Optional: Set custom model paths | |
| MODELS_DIR=/path/to/models | |
| TEMP_DIR=/path/to/temp | |
| # Optional: API keys for enhanced features | |
| HUGGINGFACE_TOKEN=your_token_here | |
| WANDB_API_KEY=your_wandb_key | |
| ``` | |
| ### Hardware Requirements | |

| - **Recommended**: 8GB+ RAM, NVIDIA GPU with CUDA | |
| - **Optimal**: 16GB+ RAM, RTX 3080+ or equivalent | |
| ## 🔧 Technical Details | |
| ### Audio Processing Pipeline | |
| 1. **Input Validation**: Check file format and size | |
| 2. **Audio Loading**: Convert to standard format (44.1kHz, 16-bit) | |
| 3. **Source Separation**: Extract vocals and instrumentals | |
| 4. **Voice Conversion**: Apply target voice characteristics | |
| 5. **Audio Mixing**: Combine converted vocals with instrumentals | |
| 6. **Post-processing**: Apply effects and format conversion | |
| ### Voice Conversion Process | |
| 1. **Feature Extraction**: Analyze vocal characteristics | |
| 2. **Model Loading**: Load target voice model | |
| 3. **Style Transfer**: Apply voice characteristics | |
| 4. **Quality Enhancement**: Improve audio quality | |
| 5. **Temporal Alignment**: Sync with original timing | |
| ## 📊 Performance | |
