Question

我正在尝试使用scipy.io.wavread读取.wav文件。它正确读取一些文件。对于某些文件，它给出了以下错误...

Warning (from warnings module):
  File "D:\project\cardiocare-1.0\src\scipy\io\wavfile.py", line 121
    warnings.warn("chunk not understood", WavFileWarning)
WavFileWarning: chunk not understood
Traceback (most recent call last):
  File "D:\project\cardiocare-1.0\src\ccare\plot.py", line 37, in plot
    input_data = read(p.bitfile)
  File "D:\project\cardiocare-1.0\src\scipy\io\wavfile.py", line 119, in read
    data = _read_data_chunk(fid, noc, bits)
  File "D:\project\cardiocare-1.0\src\scipy\io\wavfile.py", line 56, in _read_data_chunk
    data = data.reshape(-1,noc)
ValueError: total size of new array must be unchanged

任何人都可以向我建议任何解决方案吗？

我使用下面的代码来读取wav文件。我知道它不能解决你的问题，但也许你可以用这段代码读取你的wav文件，也许可以找出问题所在？

我的经验是，wav文件有时包含“奇怪”的东西，必须处理或删除。

希望它可以帮助你

import wave
import struct                     

def wavRead(fileN):
  waveFile = wave.open(fileN, 'r')   
  NbChanels = waveFile.getnchannels()
  data = []
  for x in range(NbChanels):
      data.append([])
  for i in range(0,waveFile.getnframes()):               
      waveData = waveFile.readframes(1)   
      data[i%(NbChanels)].append(int(struct.unpack("<h", waveData)[0]))

  RetAR = []
  BitDebth = waveFile.getsampwidth()*8
  for x in range(NbChanels):
       RetAR.append(np.array(data[x]))
       RetAR[-1] = RetAR[-1]/float(pow(2,(BitDebth-1)))
  fs = waveFile.getframerate()
  return RetAR,fs

无法使用scipy.io.wavread.read（）读取一些.wav文件
