input wave file sampling rate 8kHz

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Run vid -i RIFF-little-endian-16bit-8kh-wave-file.wav

Error: Traceback (most recent call last):
  File "/usr/local/bin/vid", line 132, in <module>
    thrd_n=multiprocessing.cpu_count() * 5)
  File "/usr/local/lib/python2.7/dist-packages/voiceid/sr.py", line 899, in extract_speakers
    self._to_wav()
  File "/usr/local/lib/python2.7/dist-packages/voiceid/sr.py", line 605, in _to_wav
    fm.file2wav(self.get_filename())
  File "/usr/local/lib/python2.7/dist-packages/voiceid/fm.py", line 93, in file2wav
    + "wavenc ! filesink location=" + name + ".wav ")
  File "/usr/local/lib/python2.7/dist-packages/voiceid/utils.py", line 67, in start_subprocess
    raise err

'audio/x-raw-int,rate=16000,depth=16,signed=true,channels=1' !wavenc ! filesink 
location= RIFF-little-endian-16bit-8kh-wave-file.wav]

What is the expected output? What do you see instead?
Expected: It should work with 8kHz sampled wave files as well. Or atleast give 
an exception that the file doesn't match the sampling rate.. and exits.
Actual: it gives an exception, doesn't exit cleanly and truncates the input 
wave file!

What version of the product are you using? On what operating system?
Revision: 189. URL: http://voiceid.googlecode.com/svn/trunk
Ubuntu 12.04 32bit wheezy/sid

It's a bad thing :)
We knew this problem but never had the need to fix, until your request!
Now with the revision 192 it should be fixed.
Let me know if it's ok.

• Changed state: Fixed
• Added labels: Priority-High
• Removed labels: Priority-Medium

It doesn't truncate the input wave file now. Rest is the same. When would 
voiceid be able to handle 8kHz files? Since LIUM_SpkDiarization framework uses 
8kHz as well as 16kHz, voiceid (built on top of LIUM_SpkDiarization), should be 
able to support 8kHz sampled files.

Can you attach a 8kHz file to try, with some 8kHz waves I tried it works.

Well I am at revision 192. And here is what I get:

For what I see in the traceback, you are not using the revision 192 but still 
the revision 189, because the line numbers don't match the code in that 
revision.
For example in line 605 of sr.py (rev 192) there is not what traceback says but 
you can find that very line in the revision 189.
You have to install the new version after svn up and be sure to have the right 
revision by looking at the installed files in 
/usr/local/lib/python2.7/dist-packages/voiceid/

For some reason it was giving an error on installing the new version. I 
recompiled my python installation and it worked fine :)
