I am novice at G723.1 and confuse some concept. I am Confuse with some variable in the Find_Acbk() of exec2.c. 1.ClPitchOrd=5 what does the variable mean? the LTP(Pitch predictor) filter order? 2. Hb = 3 + (Sfc & 1); what does the Hb mean? 3./* Filter the last one (ClPitchOrd-1) using the impulse responce */ ........ ........ ........ /* Update the others (ClPitchOrd-2 down to 0) */ the two step seem the RezBuf convolutin the impulse response and save into the FltBuf. but i don't understand the two step mean? Couldn't you try to explain? Hope the veteran G723.1 researcher can give me a hand. thanks . |
