You can convert MP3 directly to WAV in Python. In this article we’ll use a Python 3 to do the conversion. For this tutorial, any file will work.
To start, first install ffmpeg. ffmpeg is a free program for audio, video and multimedia processing. The program has a console interface, but except from installing it there’s not much neccessary.

Install the module pydub. This is an audio manipulation module for Python. This module can open many multimedia audio and video formats. You can install this module with pip.
pip install pydub
If you have not installed ffmpeg yet, install it. You can use your package manager to do that.
For Ubuntu / Debian Linux:
apt-get install ffmpeg
You can convert an mp3 file (src) to a wav file (dst) by changing the variable names.
The mp3 file must exist in the same directory as the program (.py). If you want to use custom directories, add a path to the filename.
from os import path

Wait for the program the complete.
