Speex dev - Aug 2004 - compression rate

Hi, 
I am very fresh man at CODEC part..
I wanna know SPEEX's compression rate..
to say , I tested wav file at 8000 Hz, 8bits to spx file.. I hoped 1/16
compression rate more..
but,, the result was not good for me..  
to say example..  I made wav file of 254Kb at 8000Hz , 8bits ...and then encode
that file..
the result was that spx file of 33.7Kb  is made... so, I though that compression
rate is 33.7 / 254 .. about 1/8..
and,,, there was noise in decoded file...
of course,, that result may be wrong because of my wrong method... 
could you let me know the best compression rate of SPEEX and parameter setting
of  good quality , good compression rate ?

The problem is that you sent Speex 8-bit input, while it expects 16
bit-linear input.
