set_audio_sample_rate
Modify the sample rate of an audio file to a specified value, saving the adjusted file to a designated path. Use this tool to ensure compatibility or optimize audio quality for specific applications.
Instructions
Sets the sample rate for an audio file. Args: input_audio_path: Path to the source audio file. output_audio_path: Path to save the audio file with the new sample rate. sample_rate: Target audio sample rate in Hz (e.g., 44100, 48000). Returns: A status message indicating success or failure.

Implementation Reference
- server.py:288-307 (handler)The handler function for the 'set_audio_sample_rate' MCP tool. It uses FFmpeg to resample the audio file to the specified sample rate (via 'ar' parameter) and handles errors gracefully.
