Access denied when using pydub

Question

I want to use this script to convert a mp3 file to a wav file.

import pydub
from pydub import AudioSegment
pydub.AudioSegment.converter=r"C:\Users\sunha\ffmpeg-4.1-win64-static\bin"
sound = AudioSegment.from_mp3("筷子兄弟 - 小苹果.mp3")
sound.export("筷子兄弟 - 小苹果.wav", format="wav")

But the problem is my access is denied.

Traceback (most recent call last):

File "<ipython-input-1-5faa7bcb6b97>", line 1, in <module>

    startupinfo)

PermissionError: [WinError 5] 拒绝访问。

How can I possibly fix the problem?

did you check, that you really have permissions for this file? — user8408080, Feb 20 '19 at 23:33
I tried to run it as administrator and it still doesn't work. — 无名氏, Feb 21 '19 at 22:39

I tried out multiple solutions, which helped me, as follows:

Rebooting the computer and/or IDE,
Updating Python, IDE, computer,
pip install pydirectory (Command/Anaconda prompt, run as administrator)
Applying read permissions to the file,
Specifying the path to the file, and adding 'r' before the path, to indicate you want to 'read' the audio file, example at the bottom.

Source

Example, run in the same folder as the audio file:

from pydub import AudioSegment
import os

os.chmod('audio2.mp3', 777)  #You might not need this

sound = AudioSegment.from_mp3(r"D:/audio.mp3")
#Put the 'r' in front of the filepath, to 'read' the audio file.
sound.export("audio.wav", format="wav")

I had the same problem, and resolved by referencing @artgue72's answer on Python Pydub Permission denied?:

I had the same issue but fixed using the GillHawk solution from this thread (same link as Jondiepdoop gave). I added f.close() in the _play_with_ffplay function of the playback.py file:
def _play_with_ffplay(seg):
with NamedTemporaryFile("w+b", suffix=".wav") as f:
    f.close() # close the file stream
    seg.export(f.name, "wav")
    subprocess.call([PLAYER, "-nodisp", "-autoexit", "-hide_banner", f.name])

In addition, please check the folder path is added to Window's Environmental Variables.

In my case, I also need no r string literal symbol before the file path, like:

sound = AudioSegment.from_file('C:\\temp\\audio1.mp3', format="mp3").
