<DIV>Hi,</DIV>
<DIV> </DIV>
<DIV>I am using speex 1.2beta2 on a narrowband 16-bit, 8khz system that has a severe program space problem and will not fit speex in its normal operation. In an attempt to shrink speex I placed a breakpoint in every function and ran a decode and encode and removed the breakpoints that I hit. in the functions that had a breakpoint that I didn't hit I commented out those functions (as well as some functions that I know I won't hit). </DIV>
<DIV> </DIV>
<DIV>I am aware that some of these functions are only not called because I don't do a GET_ in the ctl functions or don't use ALLOC to initialize the bit buffer, but some of these I am not entirely sure why they would or would not be used. I would like to know if they are just rarely called functions and that I could be breaking the codec by removing them or if all that I removed is just fine.</DIV>
<DIV> </DIV>
<DIV>I did get a .patch file from Jim Crichton as well to shrink nb_celp, but is there anything else I can do to shrink the code or am I reaching my limit? Thanks.</DIV>
