Hey guys,

I have some questions about lossyWAV and noise shaping:

Why is it white noise that is added, wouldn't it be less noticeably to use something more like pink noise?
All the noise shaping stuff I've seen tries to push noise into higher frequencies, does the opposite (lower freqs.) not make sense?

I'm mentioning this because I heard the noise with --portable, because the white noise just sticks out of the much "darker" music.
(I will provide ABX proof as soon as I'm at home..)

And, by dividing the music into blocks, I guess that the amount of noise depends on the loudness (-> noise floor?) of each block, but would it also be possible to shape the noise depending on the content of each block?
So if a hi-hat or cymbal was hit the noise would be shaped to be "hidden" behind the "crash" sound?

And my last question for now, does flac also compress most significant bits that are 0?

Thanks.
