Hi, I'm trying to create headphones EQ profiles in REW.

My software player takes in mono WAV files (doesn't have it's own parametric EQ but can do convolution etc).

Some basic adjustments like @Amir does in Roon, like below.

Can anyone share some basic steps how I would create the below profile in REW?

I got this far. I set the target to 0dB but I can't see anything like Roon has to start adding bands like Amir did

Just click on the EQ Filters button at the top, and enter the desired filter parameters. When finished, go to File->Export->Filters impulse response as WAV. Select Mono, Current Filters, 32-bit Float, and the desired sampling rate(s). Save the WAV file then use it in your convolver. Here's what it looks like for the settings you quoted from Amir:

Omg how did I not see that . Thanks heaps.

I use HQPlayer, which only takes in mono WAV impulse response files. Technically this is not an impulse response that I'm doing but it doesn't really matter right?

So this is an ok method that I'm doing?

It's the impulse response of the filters you enter. HQP 4 supports entering PEQ settings directly, bypassing REW/convolution files, but the syntax is a bit daunting from what I've seen, and I'm still on HQP 3 :)

At the moment it shows 48kHz for 'Generic'. Does that matter if I generate IR files at say 192kHz?

Generic is what you want. See the example screen capture I posted earlier:

HQPlayer will resample to the correct sampling rate, so you can pick any desired rate that matches most of your source material. The rest will be resampled, as needed.

You need Rephase to create EQ corrections in the form of a WAV file.

https://rephase.org/

REW is fully capable of doing simple PEQ in the form of a WAV file, although Rephase is also great and provides for phase corrections. Wonderful to have a choice of so many powerful software tools that don't cost a penny!

Phase corrections for headphones !?

Is anyone doing that ?

I've looked at phase response of my phones and found it to be very well behaved, no corrections necessary. For speakers -- it could be very valuable. And that's what Rephase is great for -- designing and testing crossovers, configuring subs, speaker response/room correction, etc.

Yes for speakers I use Audiolense, which is more automated than Acourate.

I'm not smart enough for Acourate or the free RePhase :-(

Is there a way to visually see the EQ curve like Roon shows in Amir's screenshot?

I've entered the values in the EQ filters box like you did.

Hi @pkane

Why is my filter curve mirrored along the x-axis, compared with Amir's?

He is boosting the areas of interest but I'm reducing those same areas ?

I created a low pass filter just to test what was happening (listened in HQP to confirm it was working as expected).

Cut-off frequency 3kHz

So the green shade above x-axis are all the frequencies being removed.

So green shade below x-axis are all frequencies being added (boosted)? It seems counter-intuitive but it is getting late and i'm tired, so maybe my brain is slower than usual at the moment LOL
