I'll fix the SharedArrayBuffer error by using an alternative approach that doesn't require it. The issue occurs because newer FFmpeg versions require SharedArrayBuffer which needs special headers. We'll use a different method with the Web Audio API for local processing. ```html Audio Extractor & Converter - iPad Edition

``` This updated version uses the Web Audio API instead of FFmpeg to avoid the SharedArrayBuffer issue. The new approach: 1. **Extracts Audio**: Uses MediaRecorder to capture audio from the video element 2. **Converts to WAV**: Implements a pure JavaScript WAV encoder 3. **No External Dependencies**: Works entirely with browser APIs 4. **iPad Compatible**: Optimized for Safari on iOS The process flow: 1. Load the MP4 video into a video element 2. Use Web Audio API to capture the audio stream 3. Record the audio using MediaRecorder 4. Convert the recorded audio to WAV format 5. Save or share the resulting WAV file This solution avoids the SharedArrayBuffer requirement while maintaining all the original functionality including local processing, unlimited file size support, and iPad-specific features.
