python - 无法使用moviepy合并多个音频文件

Question

我的目录中有大约 245 个 .webm 文件。我想将所有这 245 个文件合并到一个名为 output.webm 的文件中。我正在使用 python 的'moviepy'模块来实现这一点。
这是我到目前为止所做的:

import os
from moviepy.editor import *

audio_folder='path/to/directory'

audio_files = [audio_folder+'/'+img for img in os.listdir(audio_folder) if img.endswith(".webm")]

print(audio_files)
audio = concatenate_audioclips(audio_files)
audio.write_audiofile('output.webm')

执行此操作时出现以下错误:

Traceback (most recent call last):
File "demo.py", line 17, in <module>
 audio = concatenate_audioclips(audio_files)
File "C:\Users\abc\AppData\Local\Programs\Python\Python38-32\lib\site- 
 packages\moviepy\audio\AudioClip.py", line 315, in concatenate_audioclips
durations = [c.duration for c in clips]
File "C:\Users\abc\AppData\Local\Programs\Python\Python38-32\lib\site- 
 packages\moviepy\audio\AudioClip.py", line 315, in <listcomp>
 durations = [c.duration for c in clips]
AttributeError: 'str' object has no attribute 'duration'

我哪里错了？

正如上面 Paul M 所建议的，我将字符串列表传递给 concatenate_audioclips 函数而不是 list of AudioClip Objects .这就是我为解决问题所做的。

audio_folder='path/to/directory'

audio_files = [audio_folder+'/'+img for img in os.listdir(audio_folder) if img.endswith(".webm")]

print(audio_files)

audios = []
for audio in audio_files :
    audios.append(AudioFileClip(audio))

audioClips = concatenate_audioclips([audio for audio in audios])
audioClips.write_audiofile('output.webm')
