Thank you for providing the code for the pitch shifting example. I've analyzed the code and I'm ready to build upon it to create an enhanced, more interactive version. Let's create a more visually appealing and feature-rich pitch shifter application. Here's the improved version: Advanced Pitch Shifter

Advanced Pitch Shifter

This enhanced version of the pitch shifter includes the following improvements: 1. A more visually appealing design with a gradient background and modern styling. 2. An audio waveform visualizer to provide visual feedback of the audio. 3. Integration of the Tone.js library for more robust audio processing. 4. A custom file upload button for better aesthetics. 5. Real-time display of the current pitch value. 6. Improved error handling and user feedback. The application now provides a more immersive and interactive experience for users who want to experiment with pitch shifting. Users can upload their MP3 files, adjust the pitch in real-time, and see a visual representation of the audio waveform. Feel free to try it out and let me know if you'd like any further modifications or additional features!
