How this format loads

EqualizerAPO: the .txt goes in your config folder and is included from config.txt (the parametric filters apply system-wide on Windows). Wavelet and most DAPs accept the same band table typed into their parametric EQ: same frequencies, same gains, same Q. Preamp exists so the loudest boosted band cannot clip.

Qudelix-5K / 71: the CSV is the AutoEq interchange the app's EQ import accepts - open the EQ screen, import/paste, and the ten bands above land as parametric filters (connect the app to the dongle first). Wavelet (Android): the same CSV feeds its parametric-EQ import; on setups without import, the band table above is short enough to type in by hand. Menu names move between app versions - the numbers stay the same.

Facts on this page come from the measured curve on file; the target curve and the fit are approximations. Nothing here is a recommendation to EQ - it is the preset, labeled, for people who already EQ.
