Error with pydub in python

问题

i have successfully imported pydub but for the code:

from pydub import AudioSegment
song = AudioSegment.from_mp3("c:\mks.mp3")
first_ten_seconds = song[:10000]
song.export("d:\mks.mp3", format="mp3")

But it gives the following error:

python "C:\Users\mKs\Desktop\mks2.py"
Process started >>>
Traceback (most recent call last):
  File "C:\Users\mKs\Desktop\mks2.py", line 2, in <module>

I would love to get help on this topic

回答1:

The only issue that I see with your code is trailing ";" at the end of last 3 line. Please remove those, and see if you still get the error.

In addition, make sure you have ffmpeg (http://www.ffmpeg.org/) installed. It is required for the support of all of the none wav file formats.

ADDED:

I think you have broken module dependencies in your python installation. I have tried code that you provided above with python 2.7.2. It worked fine for me:

>>> from pydub import AudioSegment
>>> song = AudioSegment.from_wav('goodbye.wav')
>>> first_ten_seconds = song[:10000]
>>> song.export('goodbye1.wav',format='wav')
<open file 'goodbye1.wav', mode 'wb+' at 0x10cf2b270>
