Create an equalization for an IEM starting from a graph

[Stefano_Milano]

Hi everyone.
I would like to create a txt file with equalization for APO or Wavelet according to the Harman curve for the following bluetooth IEM: Soundpeats T2.
All I have is this graph.

I know how to use REW a little. How can I proceed without having the graph data but only the drawing.
Thank you
Stefano

The graph alone is useless, unless we know which ear simulator was used to create it.

To utilize the Harman target, an IEC60318-4 compliant coupler must be used.

I found this interesting article.

Sound quality isn’t a priority to many headphone manufacturers but that can be fixed without a PhD in audio engineering. Here’s how.

Great article by the AutoEQ developer!

Again though: without knowing what a frequency response graph is supposed to represent (raw FR? Compensated? If so, compensated for what? What coupler? Etc), it is darn near useless for EQ purposes.

I found it. It's raw.

Thanks again

I found that one as well.
Unfortunately, they don't say what coupler was used.
If they did, then I would've already given you a step-by-step on how to turn it into a preset
