+# 🎵 Stable Audio Open
+
+An open-source web interface for generating high-quality audio from text prompts using advanced AI models. Create music, sound effects, ambient sounds, and more with simple text descriptions.
+
+## Features
+
+- 🎼 **Text-to-Audio Generation**: Convert text prompts into audio
+- 🎚️ **Customizable Duration**: Generate audio from 1-30 seconds
+- 🎲 **Reproducible Results**: Use seeds for consistent generation
+- 🎧 **Real-time Playback**: Listen to generated audio instantly
+- 📝 **Example Prompts**: Pre-built examples to get you started
+
+## Usage
+
+1. Enter a text description of the audio you want to generate
+2. Adjust the duration slider (1-30 seconds)
+3. Optionally set a random seed for reproducible results
+4. Click "Generate Audio" to create your sound
+
+## Examples
+
+- "A gentle piano melody playing in a cozy room"
+- "Upbeat electronic dance music with synthesizers"
+- "Rain falling on a tin roof with distant thunder"
+- "Classical violin concerto with orchestra accompaniment"
+
+## Technical Details
+
+This application uses:
+- **Gradio** for the web interface
+- **PyTorch** and **Transformers** for AI model integration
+- **Stable Audio** technology for high-quality audio generation
+
+## Contributing
+
+This is an open-source project. Contributions are welcome! Feel free to:
+- Report bugs and issues
+- Suggest new features
+- Submit pull requests
+- Improve documentation
+
+## License
+
+This project is open source and available under the MIT License.
