WebSocket Audio Server

This is a FastAPI server that receives audio from an ESP32 via WebSocket, saves it, processes it (converts 32-bit to 16-bit), and sends it back for playback.

Install dependencies:
```
pip install -r requirements.txt
```

Usage

Start the server:

python server.py

Or:

uvicorn server:app --host 0.0.0.0 --port 8000

Update the IP address in main.py on your ESP32 to match your computer's IP address. Look for SERVER_IP variable.
