FileNotFoundError: [WinError 2] The system cannot find the file specified

I am trying to convert mp3 file to wav file using python!
CODE:
from os import path
from pydub import AudioSegment

files

src = "the_audio.mp3"
dst = "test.wav"

convert wav to mp3

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

Error:
FileNotFoundError Traceback (most recent call last)
