Save the code in a Python file (e.g., voice_recorder.py) and run it. The program will start recording audio from the default input device and save it as a WAV file named recording.wav.

To stop the recording, press Ctrl+C. The program will save the recorded audio and display a message confirming the successful save.

Please note that you need the pyaudio library installed to run this code. You can install it using the command pip install pyaudio.
