...ng thing is if I encode the same wav file to spx(or decode the same spx file to wav ) on Windows platform, then there is no such big clicking noise, samething is true if I use floating_point speex library to encode/decode on WM2003. Problem happens only on WM2003 using FIXED_POINT library.

...xample, when I encode the wav file to spx file, the original saved wav file does not have such noise, the noise is added only after it's converted to spx format. The floating point version of libspeex library does not give me such noise(but runs slow of course). Any suggestions? Thanks a lot!

Can you post the input and output file on the web and specify what options you're using (use speexenc/speexdec, *not* your own code).
