Steps to reproduce

This is my code

path = 'D:/VGGvox/VGGvoxtrainer/voxceleb_trainer/voxceleb/00110.m4a'
test = AudioSegment.from_file(path, 'aac')
##play(test)
test.export("test.wav", format="wav")

I got this error when I ran it

Traceback (most recent call last): File "dataprep.py", line 156, in convert(args) File "dataprep.py", line 118, in convert test = AudioSegment.from_file(path, 'aac') File "G:\Anaconda\lib\site-packages\pydub\audio_segment.py", line 717, in from_file stdout=subprocess.PIPE, stderr=subprocess.PIPE) File "G:\Anaconda\lib\subprocess.py", line 800, in init restore_signals, start_new_session) File "G:\Anaconda\lib\subprocess.py", line 1148, in _execute_child args = list2cmdline(args) File "G:\Anaconda\lib\subprocess.py", line 555, in list2cmdline needquote = (" " in arg) or ("\t" in arg) or not arg TypeError: argument of type 'NoneType' is not iterable

Expected behavior

File should converted to wav

Actual behavior

Errors show above

Your System configuration

Python version: 3.5.6
Pydub version: 0.24.1
ffmpeg or avlib?: libav
ffmpeg/avlib version: 11.3-win64

Is there an audio file you can include to help us reproduce?

You can include the audio file in this issue - just put it in a zip file and drag/drop the zip file into the github issue. I dont think the problem is my file, I have this this code with multiple files

Can you post the log output before it throws the error? There should be a line like subprocess.call(...).
