have some doubt here. For psychoacoustic model-2. There is one table that have "whigh" and "wlow" in ISO11172-3 (table D.3b) (sampling freq=44100Hz).
I use that table to construct the energy partition. Total index=b=57
The function is as follow:-
eb=sum from 'w=wlowb' to 'whighb' (rw^2)
Ofcourse my total eb will have total 57 reading since b=57.
However, for long block pre-echo control :-
nbb_l(b) = 2*nbb(b)
nbb_ll(b) = 16*nbb(b)
The problem here is qthr(b) in tablec.7.b total have index=b=63, meaning there are total 63 of qthr(b) values in the (tableC.7.b) but I only have 57 of Nbb(b) values. So can I only compare from 1 to 57 values for every block of data? Please
Are you sure you have only 57 nbb? That number should be similar to to number of qthr.. that is 63..
