[vorbis-dev] comparison of beta2 and beta3 encoder quality

[Attila Padar]

Hi,
I encoded some songs into 350 kbit/s with beta2 and beta3 too,
and I don't know why, but it seems the b2 sounds better (makes a
better quality ogg file)...
The b2 contains more the b3 contains less high sounds.
And with the b3, the size of file is smaller with 4-5%...
Do you know this problem, or do you think so, that the sound quality
is good (or better in the b3) ??

Please be carefull with the floating point calculations!
Change them only then, if it seems the new solution/routine
is surely perfect (better or same quality like in original).

Please - if you can - don't use pre-calculated floating point numbers
(i.e.: 0.34563), calculate every numbers in the program (with sin/cos/exp
function and with integer values). Somehow and somewhere the pre-calculated
numbers were also calculated...

Please use a 'typedef' for the floating point precision too (i.e. typedef
float ogg_float_t), but I would be happy if you would use 'bouble' by
default...
Or at least, the possibility of the more precision and more clear sound.

So, the Ogg Vorbis is very good, maybe with these modifications it could
be perfect too.
