Dear Aboud,
Since you’re a software wiz, you may understand this better than me:
Here are couple of web sites that have information about the *.SND source code.
I am not too sure if it contains any useful information but there is couple of utilities that you can download for free. http://oss.sgi.com/projects/audiofile/ http://www.spies.com/~franke/SoundApp/formats.html#system7

Please take a look into it and let us know…

Thanks
