Error while convering mp3 file to wav file format using python pydub module

Question

I am trying to convert my mp3 file to wav format but its giving error like this

My Code

from pydub import AudioSegment

src = "my_result.mp3"
dst = "final.wav"

sound = AudioSegment.from_mp3(src)
sound.export("final.wav",format="wav")

But this code is returning this kind of error

I think the problem is that it needs an external program such as `ffmpeg` or `ffprobe` to perform the conversion, but it could not locate that program. Do you have either of those programs installed? — John Gordon, Mar 04 '23 at 04:22
If you type `ffmpeg` at the command prompt, does the command run? Or does it say something like `ffmpeg: command not found` — John Gordon, Mar 04 '23 at 04:29
The term 'ffmpeg' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again. At line:1 char:1 — KARTX LEGEND YT, Mar 04 '23 at 04:31
Whatever directory it is installed in, you need to add that directory to your PATH environment variable. — John Gordon, Mar 04 '23 at 04:31

If your ffmpeg is installed you need to add the path of ffmpeg to your environment variables' PATH. I'll explain for windows. First, find out where your ffmpeg is installed. Record that path, because you'll need it. Use the windows search for environment variables to bring up that system menu (like this https://docs.oracle.com/en/database/oracle/machine-learning/oml4r/1.5.1/oread/creating-and-modifying-environment-variables-on-windows.html#GUID-DD6F9982-60D5-48F6-8270-A27EC53807D0). Once there, click on the variable called PATH. Then, add and paste in the path of your ffmpeg. This should allow pydub to access ffmpeg.

This is similar to this question: Pydub installation and ffmpeg which may be of further guidance in other systems.
