distinguishing file formats in libsndfile

Hi,

I was using libsndfile to read files encoded in g.726(is it alright to do so?)
and write them to an oki adpcm at 6k.
the problem is that libsndfile only accepts a combo of au and g.721
and my encoded file are headerless.
any ideas about how to work around this problem?

Thanx in advance,
Joy.M.Monteiro

libsndfile doesn't handle g.726. Maybe you could write
one and contribute it :-).

Sounds like a cool winter project to me :-)

Great!!!!!!!!!!

If this is going to be part of libsndfile at some stage, please add
a copyright notice (in your name) at the top of the file (see any 
file in libsndfile for an example) and you will need to license your 
code under the GNU LGPL (as the author, you will still be able to 
offer it separately under any other license you choose).

Your best bet would be to get the encoder and decoder working separately
from libsndfile and then, once its working, I can help you integrate it
into libsndfile. Feel free to email me for advice, but be aware that
my time to work on this is somewhat scarce. However, once you have a
working encoder and decoder, it can be integrated in a matter of hours.

Cheers,
Erik
