Cannot open audio: AttributeError: 'NoneType' object has no attribute 'start'

[AnWildDuck]

I simply can't open audio files.

Code:

import moviepy
audio = moviepy.editor.AudioFileClip('audiofil.mp3')

Error

Traceback (most recent call last):
  File "C:\Users\Johnny\AppData\Local\Programs\Python\Python35\lib\site-packages\moviepy\video\io\ffmpeg_reader.py", line 300, in ffmpeg_parse_infos
    tbr = float(line[match.start():match.end()].split(' ')[1])
ValueError: could not convert string to float: '90k'

During handling of the above exception, another exception occurred:

    audio = moviepy.editor.AudioFileClip('audio\\Scheming Weasel faster.mp3')

Can you post the audio file it fails on please? Is it only one, or have you tried several? Have you tried updating moviepy to the latest version?

issue #448 has the same issue, and they have supplied an audio file so we can reproduce the error.
In the zip file that request we download look at the file 01\ Demacia\ Rising.mp3.

_clip = AudioClipFile(r"01 Demacia Rising.mp3")

The code above will reproduce the error.

fixed with pull request #449. Try pulling from repo, and if issue still exists, let us know.
