I had 2 wav files , that I had been using since the past , and they work perfectly with scipy wave read function , but when I added a new file , it threw following error

Traceback (most recent call last):
  File "multidata.py", line 83, in <module>
    fs[i], audio[i] = wav.read(audio_filename[i])
  File "/home/saurabh/anaconda3/envs/py27/lib/python2.7/site-packages/scipy/io/wavfile.py", line 236, in read
    file_size, is_big_endian = _read_riff_chunk(fid)
  File "/home/saurabh/anaconda3/envs/py27/lib/python2.7/site-packages/scipy/io/wavfile.py", line 168, in _read_riff_chunk
    "understood.".format(repr(str1)))
ValueError: File format '<htm'... not understood.

I have tried recording with sox , arecord and audacity , also made sure there is no metadata , I have also tried all possible settings like mono , 16 bit , 16000 hertz etc , It doesn’t work , even the settings matching with two wav files which the function is able to read

Reproducing code example:

<<A short code example that reproduces the problem. It should be self-contained, i.e., possible to run as-is via 'python myproblem.py'>>

for i,j in enumerate(wav_files): print (i,j) audio_filename[i] = maybe_download(j + ‘.wav’) print ( audio_filename[i]) #print (audio_filename) target_filename[i] = maybe_download(j + ‘.txt’) fs[i], audio[i] = wav.read(audio_filename[i]) #print (audio[i])

maybe_download is a function that checks if file exists locally , otherwise downloads it
