有没有一种简单的方法可以在python中加载m4a声音文件.我遇到过audiotools lib，但是在使用to_pcm fn
Is there an easy way to load m4a sound file in python. I've came across audiotools lib but I'm getting an error while using to_pcm fn
audiotools.open('file.m4a').to_pcm()

推荐答案
以下是使用 pydub 的方法>库:
Here's how you would do it using the pydub library:
from pydub import AudioSegment
audio = AudioSegment.from_file('file.m4a')
