it seems the negative taper values help out alot with the signal when encoding with flac. i dont think flac enthusists that have been using flac for a long time since the beginning of the format missed the importance of negative values inside the tukey functions. also having the setup up to punchout regular and tukey makes up for a consileable mix for the accurateness of the signal over certain context of functions in the right order. the negative gauss values have a value of accuracy also. so as much i have experimented i should know now that the negative values go with the complexity of the function ordering. whereas now i go forward with flac i must find a way to find the power and amp specific functions inside my setups where i should be heading into playing around with certain gradual pad with some high and low variation tapering where the specific result will show up in the listening where i can have the experimentation echo the right variation into the accuracy the flac format had in its picture as a format in such that the format has the right programming for the right adjustments. moreso the adjustment parts are more latin and i cant find any documentation on just how the setups go hand in hand in sorting out what makes up the accuracies when puting the setup to its generalized purpose. no documentation in no direction of sources i looked up on the internet and im left to exposing the format intricates in my formulation as an end user (with no documentation).....
