flac dev - Feb 2015 - about apodization functions

Hi Guys,

Does having multiple apodization functions change something to the 
decoding process
or does it only apply to the encoding process ?

I have been able to gain almost 10% by using several apodization 
functions (it takes way more time to encode but this is quite a non 
issue in my use case)
but I don't want to sacrifice any decoding speed as this is the 
bottleneck for me.

Thanks,

It is only applicable to encoding, it is probably best to see it 
as more 'analysation passes'. I wonder how you got to 10% gain 
though, usually gains are more in the order or 0.1% or something 
like that.

Well I'm not testing on music material but on a single piano note of 1 min
length
and went from a 0.156 to a 0.148 ratio

Thanks for the answer.
