First post here, hi everyone. One point in Toole`s book is the need for an (easy) loudness correction/control. Beyond personal preferences, if I understood correctly, no matter how flat or house curve adjusted (or not), the way we perceive/hear the bass (<200Hz) is much dependent on level/volume the program is actually played. So if an engineer heard and adjusted for a good bass balance in the final recording it was done at a certain level, say, 80db. Toole says in his book whenever we hear it at a different level, we will have a different perception of the bass (mainly) levels (explained by the difference of equal loudness contour curves, ELCC, at specific phons). The figures attached are from his book reflecting those adjustments. It seems that a static curve (house or otherwise) is a poor attempt, and just applies to the average difference/listener preference.
What I am looking for is a dynamic equalizer or loudness control or vst filter/dsp hardware/dynamic convolution or even an analog one that works dynamically, at play time time, adjusting the loudness based on the volume level and those ELCC. If software, it could be plugged into JRiver, Roon or into another player app. Basically it has a settable reference level, and from there it adjusts according to the curves and volume. Does it make sense? Anyone aware of such a device/app/plug-in?
