For Iphone, I can't tell... But for PCC (win, linux) you can use REW, a very powerful tool for measurement.
And I suggest you to use brutefir plugin,, you get something very good in a easy way ! : https://github.com/balbuze/volumio-plugins/tree/master/plugins/audio_interface/brutefir3

Thanks Balbuze, this sounds very promising! So what I measure in REW will be loaded into the brutefir plugin? After that no other equalizer will be needed?

hi!
the most important is to make a good measure from your listening point for both channel separately.
once it is done, you export impulse (for each chanel) and copy the file in /brutefirfilters/filter_sources
After that go in the plugin setting and usr 'DRC-FIR' to generate your filters. once it is done, select filters for each channel, apply, it's done! you have now a room equalized system ;)

Hello,
Should this plugin work in Volumio Primo?
I have installed it but does not output any sound.
Thanks.

Hi Balbuze, I have the UMIK-1 connected to REW on a laptop. Is there a way to send the measurement signal from REW to volumio on the PI? In the REW soundcard preferences I don't see an option for that. Thanks!

to continue to talk about brutefir and drc, I suggest to use the dedicated thread : https://forum.volumio.org/volumio2-and-brutefir-t4151-310.html
and have a look here : https://volumio.github.io/docs/Plugins_User_Manuals/brutefir/Making_Measurment.html

edit : @juan - yes it works with primo ;)

Hi balbuze, I'm testing REW and I have a question:
To generate the EQ Filters, what equalizer data should I set in the "EQ for Measurement" menu, Equalizer tab?

Sorry but I am not sure to understand what you want to do. With parametric EQ, you don't use Rew, except to check the result. If you're asking for brutefir plugin, please post in the related thread. And check the wiki TY

I am trying to understand how brutefir / rew / eq works, I ask you to be patient.
I started measuring the room, that seems to be pretty good.
When I ask you to equalize the signal, it does it over 10 bands in the case of using the "Generic" equalizer, using other eqs it does in another number of bands, never in 4 bands as your parametric equalizer works.
My idea is to equalize "by hand" as obtained in REW.
I will read more about Brutefir and implement it.
