There is some more about CD pre-emphasis here: Pre-emphasis - Hydrogenaudio Knowledgebase.
However since some CD rippers these days detect pre-emphasised CD’s and apply a de-emphasis filter, you would need to know what ripper processed the files before deciding to use the filter.

Sorry, i bad english.
I experiment with longer EQ curves:
http://pvtv.hu/tarolo/out_files/EQgen.tar.xz
ultima.XML (21.4 KB)
Use audacity as equalizer.
At home and in the car.
Place a curve in the case of utilities’ other forum friends who may like me
use audacity to equalize the tracks.
Great program.
Thanks to the team of Audacity.
Thank you, I moved your post to this topic where we store user’s suggested EQ curves.
How would you describe the purpose and special qualities of your curve?

Audacity curve EQ.XML (20 KB)
Thanks but there is not much point posting a curve with a generic name and no other indication what it should be used for.
Is it supposed to be a curve for a specific genre of music?

EQ curve generator in javascript, calculate sound resonances in cavity.
Thanks, that’s a nice project.
Could you extend it to include 3 dimensions along with a material quotient? 
… to include 3 dimensions …
2 channel → one (or more) effect per channel, with different values.
I thinking this, at least two curves to be generated.

can you please put a range text window into this generator?
anyone got a ITU-R 468 weighted curve?
I’ve not seen one posted, but you can get the figures to create one yourself from here: ITU-R 468 noise weighting - Wikipedia
If you need help converting those figures into a EQ Curve file, please ask. If you manage to do it yourself, please feel free to post your file to this forum topic.
welllll,
that made me learn some new things about LibreOffice Calc 
If someone needs another “version” I can do it very quick now in my sheet
here it is normalized and inverted:
