...clean way I could change the NB mode buffer size to be 256, which would be a little closer 20ms at 11025 but also be divisible by 2048. Should I add a new custom mode to the modes array or should I mess with the NB mode? Any advice on what I should do with subFrameSize and the other parameters in SpeexNBMode (if anything) if I change the framesize to be 256? Thanks, Dave

...n looking over the code so I may have been absolutely wrong. The main assumption was about the exc tables. In looking through modes.c it appeared that only one table was required for 8kbs so I commented out the portions of the code that referenced the other tables and modified "static const SpeexNBMode nb_mode" structure so that the pointers to the other structures that referenced the tables were NULL. We did not have enough data memory to store all the tables. I thought this would work with my initialization but when I stepped through the code in nb_celp for encode it would put it in mode...
