I had a problem when reading the wav file

[wangshaoce]

log：
/Users/wangshaoce/test_project/pysepm/test.py:6: WavFileWarning: Chunk (non-data) not understood, skipping it.
fs, clean_speech = scipy.io.wavfile.read('1_speech_16000_Hz.wav')
/Users/wangshaoce/test_project/pysepm/test.py:7: WavFileWarning: Chunk (non-data) not understood, skipping it.
fs, noisy_speech = scipy.io.wavfile.read('1_noisySpeech_16000_Hz.wav')
this is my code：
import pysepm
import scipy.io.wavfile
import wavio
import sys
sys.path.append("../")
fs, clean_speech = scipy.io.wavfile.read('1_speech_16000_Hz.wav')
fs, noisy_speech = scipy.io.wavfile.read('1_noisySpeech_16000_Hz.wav')

fs, enhanced_speech = scipy.io.wavfile.read('1_processed_16000_Hz.wav')

pysepm.pesq(clean_speech, noisy_speech, fs)

pysepm.pesq(clean_speech, enhanced_speech, fs)

Google didn't solve my problem
I look forward to your reply
best wishes

Hi wangshaoce

I think it shouldn't be a problem (it's just a warning). Scipy's wav read function just can't read some of the wav file's meta data. But this should have no influence on the audio signal.
If you don't like the warning, just write the signals with Scipy's wav write function to new files (meta data will be removed) and read this files again.
