Wavefile.read 给出文件格式 b'\x00\x00\x00\x1c'...不理解

Question

我正在尝试用 python 读取波形文件

from scipy.io import wavfile
fname = "good.wav"
sample_rate, samples = wavfile.read(fname)

但是我收到以下错误消息：

ValueError                                Traceback (most recent call last)
<ipython-input-4-ae3602287699> in <module>
      3 from scipy.io import wavfile
      4 
----> 5 sample_rate, samples = wavfile.read(fname)
      6 frequencies, times, spectrogram = signal.spectrogram(samples, sample_rate)
      7 

in read(filename, mmap)
    234 
    235     try:
--> 236         file_size, is_big_endian = _read_riff_chunk(fid)
    237         fmt_chunk_received = False
    238         channels = 1

 in _read_riff_chunk(fid)
    166         # There are also .wav files with "FFIR" or "XFIR" signatures?
    167         raise ValueError("File format {}... not "
--> 168                          "understood.".format(repr(str1)))
    169 
    170     # Size of entire file

ValueError: File format b'\x00\x00\x00\x1c'... not understood.

我想我需要先以某种方式将我的文件转换为不同的波形文件，因为它可以正确播放。任何人都可以提示如何在 Mac 上理想地执行此操作。
