...ook and innovation codebook. what are the tools to train the pitch and innovation codebook? Regarding the pitch prediction for high-band, I understand your reason of not using it for high-band. There is one paper, "A 14 kb/s wideband speech coder with a parametric highband model" by A. McCree (ICASSP 2000), Vol. 2, pp. II 1153 - II 1156, which use similar QMF filters and then suggests some ways for frequency reversal. So will it be feasible to implement here in our case ? After frequency reversal we can use same pitch prediction as narrowband does. dev Jean-Marc Valin <Jean-Ma...

Hi, Can someone please tell me how should I go about changing the frame size which is hardcoded to 160 for NB and WB and 320 for UWB. For NB speech(8KHz) the framesize of 160 is 20ms frame but for WB and UWB its 10ms. What are the parameters being affected by simply changing the framesize and sub-frame size in "modes.c" How to change the buffer size and how its affected. can we have a
