Select Encode/Decode operation\n   - Browse for input file or enter text directly\n   - Choose from 15 encoding modes\n   - Configure options and click Start\n\n## 📋 Encoding Modes\n\n### Text-Based\n\n- **Base32/64/85/91**: Standard text encoding formats\n- **Binary/Hex**: Simple binary representations\n- **Braille**: Unicode Braille character mapping\n\n### Visual\n\n- **QR Code**: Scannable 2D codes with error correction\n- **Barcode**: Professional 1D barcodes with custom text\n- **Image**: Data encoded as RGB pixels in PNG\n- **Chess**: Interactive chess board positions\n- **Sudoku**: Puzzle grid coordinates\n\n### Audio/Creative\n\n- **Sound (MIDI)**: Musical note sequences\n- **Emoji**: Emoji character sequences\n- **UUID**: UUID-embedded data\n\n### Steganographic\n\n- **Zero-Width**: Invisible Unicode characters\n- **Image Steganography**: Hidden pixel data\n\n## ⚙️ Key Features\n\n- **🔍 Smart Search**: Find modes quickly with Ctrl+F\n- **🔐 XOR Encryption**: Optional key-based security\n- **📊 Interactive Viewers**: Chess and Sudoku visualization\n- **⚡ Progress Tracking**: Real-time processing feedback\n- **🎨 Dynamic Options**: Context-sensitive settings\n- **📁 Auto Organization**: Separate human/machine file directories\n\n## 🛠️ Mode Options\n\nDifferent modes offer specific customization options:\n\n- **QR Code**: Error correction level, size, border\n- **Barcode**: Type, dimensions (mm), custom text, font size (pt)\n- **Sound**: Encoding method, tempo, note duration\n- **Sudoku**: Grid seed, shuffle key, format style\n- **Chess**: Interactive viewer, PNG export\n- **Emoji**: Shuffle patterns for obfuscation\n- **Image**: PNG compression levels (0-9)\n\n## 🔒 Security\n\n- **XOR Encryption**: Apply to any mode using custom keys\n- **Random Filenames**: Hide original file names\n- **Steganographic Modes**: Multiple hidden data techniques\n- **Visual Obfuscation**: Emoji shuffling, chess positions\n\n## 📁 Directory Structure\n\n```\n├── main.py              # Application entry point\n├── human_files/         # Original files (input)\n├── machine_files/       # Encoded files (output)\n├── chess_images/        # Chess viewer exports\n├── fonts/               # FiraCode font files\n├── src/                 # Source code modules\n└── requirements.txt     # Dependencies\n```\n\n## 📦 Requirements\n\n- Python 3.6+\n- Pillow (image processing)\n- qrcode (QR code generation)\n- pyzbar (barcode reading)\n- tkinter (GUI - included with Python)\n\n## 📖 Test Files\n\nThe `human_files/` directory includes sample test files for trying different encoding modes:\n\n- `simple_text.txt` - Basic text for all modes\n- `unicode_test.txt` - Multi-language and emoji content\n- `quick_test.txt` - Small file for fast testing\n- Mode-specific test files for optimal results\n- `README_TEST_FILES.md` - Detailed usage guide\n\n## 🎯 Performance Tips\n\n- **Small files** (\u003c100KB): All settings work well\n- **Large files** (\u003e1MB): Use optimized settings for MIDI mode\n- **MIDI playback**: Default ultra-fast settings reduce hours to minutes\n- **Search**: Use Ctrl+F to quickly find the right encoding mode\n\n## 📄 License\n\nMIT License -
