Hi, you got your link from Oratory's listing on reddit right, in that case then that's fine.
Yes, you input the figures into Peace from the black box at the bottom of the pdf file (the box is labelled "Filter Settings").
The changes you make in Peace / EqualiserAPO are boot persistent, in as much as you don't need to run the program each time you start up your PC - it remembers the settings you last inputted via Peace / EqualiserAPO...it changes/writes something in the Windows Audio Chain that is boot persistent. Mind you, I'm a bit of a stickler and load up EqualiserAPO (I don't use Peace) each time I listen to music to check that it's configured properly, and to make sure that it's applying it's effect.....even though I know this is not necessary, ha!
Thanks for the reply. That clears up my confusion in relation to using equaliser. Is there any other tips or precautions when using such program?
