Hello,
I am trying to know about how speex encoding and decoding actually works so i have imported the project provided by speex for C55x processors
This simulation actually accepts a .snd file and compress and decompresses it and gives out a .snd file so in the even of this when i try to input a speech file in .snd format the console gives me something like this

SNR = 0.761611
segmental SNR = 0.766965
frankly i did not understand these console messages,any one can explain if they have worked
so from this i feel the speex has no enough space to do the necessary operation or
here is the command file for you

is it an internal setting error ?
i have attached the sound file and also the project
if you are unable to compile it import directly as legacy from
here :http://downloads.xiph.org/releases/speex/speex-1.2beta3.tar.gz
1.necessary changes needed are patch config.h and os_support_custom.h in to include folder or any desired path
patch here:6683.patch.zip
2.changing include path
3.editing arch.h with #define FIXED_POINT
please resolve my error if any one of you have ported speex on to C55x platform
