Harman Headphone Target Curve

[foolion]

Hi everyone,

Good to find a good place to talk about calibration here.
I'm very interested in headphone calibration recently.
So does any one has a txt version of harman headphone target curve or a calibration file.

Thanks a lot!

I haven't seen a file of the target curve, but if you have an image of it you could generate a file using Engauge Digitizer or similar.

Thank you so much, my friend!!
I'll try it.

the curve is like that

The digitising software will probably have an easier time if you can find an image with just the target of interest, those curves are so close in places it may struggle to distinguish them and lose the trace it is trying to follow.

You can also generate a file with VituixCad :

A separate file should be created for each curve by erasing the other three colors with a simple application like Paint. It's a little tedious but it's feasible!

Thank you Berbard! I'm trying to use that now.

I just notice that you are the Author of REW.
Thank you SO MUCH, John!
REW is one of the best two software I've ever use (another is Reaper)
Many many appreciate.

Hi Foolion,
here they are

Hello
OE2013 curve : a trial with VituixCAD2.
Keep in mind that it isn't very precise.

Thank you so much! All of you!
Now I've learned how to use VituixCAD.

There is another problem that I'm facing.
Since I'm using a FIR processor to make the calibration.
I need to transfer the harman curve into a FIR curve.
The data is like this attachment.
Thanks a lot!!
