...the range of +- 16 bit numbers. Is is it just a 32767
factor difference?
2) In the "4.2.7.9.1. LTP Synthesis" section you have to loop through
all the sub frames. J is the index of the first sample in the current
sub-frame. The first voiced res[i] calculation loops through the range
j - pitch_lags[s] - 2) <= i < out_end
For the first sub-frame j = 0 (its basically s*n and s = 0) so i
starts off negative. Couple of questions here.
What is the first / second res[i] calc actually doing? How do you
interpret the negative index?
Out_end is either (j - (s-2)*n) or (j - s*n), if the sub-fr...
