Subject: [PATCH] Add Simple interactive audio recorder script

# Audio Recorder (crypto.py)

Simple interactive audio recorder script that uses sounddevice and wavio to record microphone input and save as a WAV file.

## Features
- List available audio input devices
- Record audio for a user-specified duration
- Configure device index, sample rate, channels and output filename
- Saves recording as a .wav file
