Преобразование файлов MP3 в файлы WAV с использованием python

Question

Я пытаюсь преобразовать mp3-файл в wav-файл, используя python. Я использую IDLE 3.7.4. У меня установлены pydub и Ffmpeg. Я считаю, что все установил правильно, но не уверен, почему мой файл не будет конвертирован из mp3 в wav .., пожалуйста, помогите мне

input:

    from pydub import AudioSegment
    sound = AudioSegment.from_mp3("/Users/audio.mp3")
    sound.export("/Users/file.wav", format="wav")





output:
