[Speex-dev] Speex: getting started

I'm an Italian student in computer engineering (University "Federico II" of
Naples) and I have to write my graduation thesis in the field of signal
processing. My teacher (Prof. Giovanni Poggi
http://www.diet.unina.it/giovanni.poggi/) has published a research about
multiple description vector quantizers by means of the self organizing maps,
applying his idea to the images and now I look after audio.

So I have looked for an open source codec and I have found Speex! I should
modify the "vector quantization"  in the "multiple description vector
quantization". Can you help me?

For a start, after I have read all the manual, I have considered the function
"testenc" in "libspeex"  to understand the process of coding/decoding. Can you
tell me what parameters I have to pass along main function from command line?
In particular, What format must have the files? How can I create a file in the
format ".sw"?

Thank you!
