Need info on G.723.1 .wav format

Need info on G.723.1 .wav format

[Devendra Jalihal]

I am sorry for sending this mail to linux-sound group. It is not very
pertinent to this group. But, I don't know where to send it. So, here it
goes.

We have our own implementation of G.723.1 speech compression @ 6.3 kbps
(it is a licenced codec and not a free one). I would like to output the
compressed bits in .wav format. Can somebody direct me to the site where I
can get info about .wav in general and specifically about G.723.1 based
.wav? Is there an IETF recommendation on .wav? An RFC? Where can I get
info about .wav? Which body  makes the .wav standard?

I would really appreciate any info that you can give me.

afaik, it's not a standard at all. it's what microsoft uses, so
everyone has to use it, too.
chris bagwell's audio file format faq should be useful:

I appreciate that you're looking for any help possible, but it is somewhat 
of an insult to email an open source project mailling list requesting for 
help regarding a proprietory project you're working on. Perhaps you'd be 
better off using your company's resources to acquire said information.

Perhaps I should explain. We are not a company. We are a research group of
the Indian Institute of Technology working on some ideas to make internet
relevant to India. We are a not-for-profit group. I would appreciate any
positive inputs you can give. Flames are not very useful. India is a hot
country anyway :-)
