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 (t1)
t=1/t
Rfthr= max(Rthr*t, min (Rthr, bmax*Rengy))
*Lfthr=
Hi Mark,
Assume that input is uniform 1kHz sin wave. When we analyze spectrum of
this input using 1024 point FFT, not only one spectral line appears, like
this:

This causes peak detection difficult. I want only one spectral line appear
on this case.

Take a look at your 'factor' - this is called bmax or BMLD protection
ratio. If you find a BMLD formula you will notice

Hi all,
Just to inquire more about MS Stereo. I am confused about how the block is
decided between long and short blocks.
In the previous algorithm, the blocks are decided based on LR thresholds
after L3psycho_anal. Is that true? Can't we use the final LR/MS thresholds ie
fthr for the block
hi
i have some
question about the ms thresholdinaac
first , the
mthr/sthr what is it mean?
second, why
the BMLD only depend on energy
thank for anwer

Hi all,
I am a student doing a project to add MS to the dist10 code. I had
implemented the JStereo/MS stereo to the code. The default is now MS. There is no
switch yet on the code. However, the quality of the sound is similar to L/R and
compare to Fhg, it is not as good. According to the 1172-3
