G728 codec, synchronization

Jump to solution
I'm using IPPG728 voice codec, my code is using USC from IPP Samples.
I want to generate in-band sinchronization, as described in G728 3.11.
While robbing synchronization bit I should search not the whole shape codebook but only the half. For shape codebook search CodebookSearch_G728 function is used. Unfortunately it doesn't allow me to control codebook search process.

Is there any way to implement 3.11 section of G728?

G728 in-bandsynchronization described in ITU-G728 3.11 is not supportedin IPP library.It will require new IPP function development.You maysubmitthisnew feature request thruhttp://premier.intel.com,registration required.
