How to convert m4a file into mp3 file in Python

Today, I will show how to convert m4a file into mp3 file in python.

My test environment is OS : Windows 10 and Python version : 3.7.6

 

Convert m4a file into mp3 file in Python

 

Firstly, you need to install python library "pydub" 

GitHub - jiaaro/pydub: Manipulate audio with a simple and easy high level interface

 

But to use pydub library, you need to install ffmpeg or libav.

FFmpeg

GitHub - libav/libav: Libav github mirror, clone of git://git.libav.org/libav

 

You can install ffmpeg-downloader package with below command.

pip install ffmpeg-downloader
ffdl install --add-path

The --add-path option adds the installed FFmpeg folder to the user's system path. In Windows, you need to add your PATH to use ffmpeg library. After add PATH, please reopen python interpretor or other script editor to run ffmpeg properly.

 

If you have other OS, you can check ffmpeg homepage or pydub github page. They explain details how to install ffmpeg in your OS.

 

I provide you sample m4a file to test your script. You can see more free m4a files here.

sample3.m4a

1.66MB

 

 

The sample source code is below.

from pydub import AudioSegment

song = AudioSegment.from_file("sample3.m4a")
song.export("sample3.mp3", format="mp3")

 

If you look at pydub github page, you can convert m4a file into any audio format file.
