[CELT-dev] FIXED_POINT

[Riccardo Micci]

Hi,
I've recently successful built and run CELT under Windows using 
"testcelt.c" example file. Since I'm about to port it on a embedded 
platform i activated the FIXED_POINT #define.
I included fixed_generic.h and without other changes to the code i tried 
to encode and decode the same file i previously used.
The output though is completely saturated i.e. it jumps from -32768 to 
+32767.
I then tried decoding an encoded in floating point mode file with a fixed 
point decoder and the other way around. Both are not working.
I'm using CELT 0.7.1.
It shouldn't be relevant but the source file is 
freq: 32000
channels: 1
frame_size = 256 
bytes_per_packet = 64.

Has anybody had my same problem? Any suggestion?
Thanks

Regards
Riccardo
