Need optimum adaptive codebook gains in G.723.1 - koro - Apr 8 6:41:00 2004
|
Dear all! I am fresh in speech coding, and now I use the G.723.1 to compress our TTS database. I want to retrain the two gain tables used in the adaptive codebook which are 85 and 170 entries. Now I need the "optimum" values(i.e.,the unquantized values) of those 5 coefficients. But in G.723.1 it seems that the coder does not calculate the optimum coefficients. So how can I obtain these values? Thanks in advance! |
