Hi all,
I had been reading the mail archive. One of the mail by Menno Bakker from
FAAC dated Wed, 15 Dec 1999 mentioned AAC MS Stereo implemention ie
bmax(b) = pow(10, -3*(0.5+0.5*cos(Pi*(min(bval(b),15.5)/15.5)))
t=Mthr/Sthr
if (t>1)
t=1/t
Rfthr= max(Rthr*t, min (Rthr, bmax*Rengy))
*Lfthr= max(Lthr*t, min (Lthr, bmax) *Lengy)
t=min(Lthr, Rthr)
Mfthr=min(t, max(Mthr, min(Sengy*bmax,Sthr) )
Sfthr=min(t, max(Sthr, min(Mengy*bmax,Mthr) )
*Lfthr= max(Lthr*t, min (Lthr, bmax*Lengy)) I think there is a slight typo
error....
I notice there are some similarities as well as differences. I am sorry if I
sound ignorant but can anyone explain the rational of using Johnston and
Ferreira algorithm rather than the one above. For instance, Lame does not
calculate final thr for LR etc
Will appreciate anyone willing to clear my doubt....
