[maemo-developers] [maemo-developers] maemo-recorder and iLBC conversion

I have used recently maemo-recorder to record about two hours of
speech, using the iLBC audio format. To my surprise, i discovered that
is very hard to find a way to convert this audio format to a more
common one.
I also noted that this issue was already pointed out in this list.

After many searches, i finally opted for slightly modifying the
reference code in  rfc3951 http://www.ietf.org/rfc/rfc3951.txt ,
following the directions in http://www.ilbcfreeware.org/software.html

I guess that I cannot publicize the code for licencing raesons, but
the modifications are really trivial.

The resulting raw pcm file can be easily manipulated using sox:
 sox -t raw -s -w -c 1 -r 8000 sounndfile.pcm  soundfile.wav

I post here hoping this could help someone.
