Answer 1

It is a very easy Task using ffmpeg with python subprocess and there is a reason why people are pointing to this solution as a good solution.

This is the basic command extracting audio from a given video File:

ffmpeg -i test.mp4 -ab 160k -ac 2 -ar 44100 -vn audio.wav

The Python Code is just wrapping this command:

import subprocess

command = "ffmpeg -i C:/test.mp4 -ab 160k -ac 2 -ar 44100 -vn audio.wav"

subprocess.call(command, shell=True)

You have to make sure that ffmpeg is a known task, so in your system environment variables, under path, the path to ffmpeg.exe should be listed, or you can just use the full path to the exe in your python code.
