trying the encodings are good for thinking along the line of measuring exactly what you want out of the flac custom setup but ususally ive been doing it without paying attention to the LPC and Residual Coding slider bars on the freac encoder window where i put in the custom window list. somehow the list remains usually what i want but setting up the sliders to the point of having the listening result up to a good measurement is kind of confusing. if you have the energy to adjust the slider in just the right position for the encoding that would be good because i think the sliders affect exactly the right quality effect for what the encoding is suppose to look like in the end result in mostly the proper order of using the software. a proper take would be reading on what the LPC and residual coding value does and then using that thinking for how your going to setup the results. i just adjust and listen and make more adjustments. im thinking though the sony player has a little private company side to the way they put their device up to the quality issue when at any point the owner of the device would kind of play their rule in measureing things like this. there is definitely a private protected side to the sony player that sony didnt want all the way manageable in this case when measuring then listening. very strange and with me i get to some frustration.
