如何在python中加载m4a文件

Question

有没有一种简单的方法可以在python中加载m4a声音文件。我遇到了audiotools库，但在使用to_pcmfn时遇到了一个错误

audiotools.open('file.m4a').to_pcm()

    457             stderr=subprocess.DEVNULL if hasattr(subprocess, "DEVNULL") else
--> 458             open(os.devnull, "wb"))
    459         return PCMFileReader(sub.stdout,

   1334                 raise child_exception_type(err_msg)
   1335 

FileNotFoundError: [Errno 2] No such file or directory: 'faad'

下面是使用pydub库进行操作的方法：

from pydub import AudioSegment
audio = AudioSegment.from_file('file.m4a')
