96 kHz 24 bit audio files not supported

[audiofeature]

I used wavio.py 0.0.1 for quite a while but just installed wavio-0.0.3 freshly via pip.

In both cases, on an 96 kHz 24 bit audio file I get the following error (0.0.3 in this case).

from wavio import read
Wav = read('000042B1-0005294207.wav')
Traceback (most recent call last):
File "", line 1, in
File "/usr/local/lib/python2.7/dist-packages/wavio.py", line 164, in read
wav = _wave.open(file)
File "/usr/lib/python2.7/wave.py", line 511, in open
return Wave_read(f)
File "/usr/lib/python2.7/wave.py", line 164, in init
self.initfp(f)
File "/usr/lib/python2.7/wave.py", line 144, in initfp
self._read_fmt_chunk(chunk)
File "/usr/lib/python2.7/wave.py", line 274, in _read_fmt_chunk
raise Error, 'unknown format: %r' % (wFormatTag,)
wave.Error: unknown format: 65534

The linux 'file' command however correctly identifies the file format:

file 000042B1-0005294207.wav
000042B1-0005294207.wav: RIFF (little-endian) data, WAVE audio, stereo 96000 Hz

Is 96 kHz / 24 bit audio format a doable thing?

Just realized the problem is in Pythons wave package and reported here
jiaaro/pydub#129
and here
http://stackoverflow.com/questions/29000788/large-wave-file-not-being-read-in-python

saying:
Format 65534 is a format called WAVE_FORMAT_EXTENSIBLE defined by Microsoft and is used for multi-channel wave files. It's pretty uncommon.

I guess I should close this issue as wont fix by wavio.

Thanks for tracking down the source of the problem. wavio relies on the Python wave standard library, so if wave can't handle it, wavio also can't handle it.
