This allows for easy de-emphasis of CDs in relatively high ("ideal") resolution.
There is some more about CD pre-emphasis here: http://wiki.hydrogenaud.io/index.php?title=Pre-emphasis.

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.

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?

First, the sony-oxford R3 EQs from this page:
http://www.sonnoxplugins.com/pub/plugin ... le2-eq.htm

Second, http://sjeng.org/ftp/fb2k/eq_presets.zip

Those are .feq presets for Foobar 2000, but they are plain text files with 18 gain values for the following frequencies in Hz:

55, 77, 110, 156, 220, 311, 440, 622, 880, 1200, 1800, 2500, 3500, 5000, 7000, 10000, 14000, 20000

The 20 presets in the zip are:

1965
Air
Brittle
Car Stereo
Classic V
Clear
Dark
DEATH
Drums
Flat
Home Theater
Loudness
Metal
Pop
Premaster
Presence
Punch & Sparkle
Shimmer
Soft Bass
Strings

More explanation of how to use the above data is at http://forum.audacityteam.org/viewtopic ... 01#p203701 .

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?

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.
