Room correction

Hello everyone! I was really excited to see my wiim pro plus now has room correction. However, it is not audible at all. Did anyone experience the same?
Everything seems to work fine: I hear the sound it makes when calibrating, I hold the I-phone on the indicated position, it shows a graph and the list of the EQ corrections it performs... but no difference whatsoever (I have tried many times, even AB test with eyes closed and my finger activating and desactivating the filter on the app)
The EQ per se works fine, if I mess dropping the highs or lows it is audible, or if I use one of the standard EQ settings (loudness, piano, bass booster,...)
Obviously I am doing sth wrong with room correction but can't seem to figure out what it may be... any ideas?
Thank you so much in advance!

Are you applying the Room Correction to the input you are listening to?
 
I have been searching for a way to apply room correction to a specific input but could not find it.
I had always assumed that any correction with EQ would affect sound as long as the wiim pro plus was playing (like for instance if I turn down one of the sliders on the graphic EQ it is audible almost immediately, without having to specify which input I want to apply it to)

If you are on the EQ screen at the top…
 
I found three different options for the curve: B&K, Harman and Flat (so far I have used B&K since it seems to be the default one), I'll try them all just in case...

Thank you for your quick responses, that is really kind
 
How does the correction curve looks like?
It should be „active“ and stored under „auto“ when you enter EQ after RC.
 
only concerning ios for the moment... which is really the interesting thing in the case of captures via phone...(not the """rew qualibred micro""" etc of course),

it is really the objective and subjective comparisons with housecurve, soft little expensive and having perspective, for example, which seems the most interesting to me..."sames conditions"...
for the moment...

any observations? ;-)

I have lately with last version of app and firmware run another correction with B&K and no restriction in the q or gain . I have entered the setting in rew and showed me that I need 2.67db of headroom . So the volume of 95% was covering it.

Now I run HouseCurve after Wiim room correction and it confirms the curve using again the iPhone mic.

I see a spike in group delay though and I don’t know if it is related the peq . Not talking about the lowest frequencies my speakers do not produce any usable output , I am referring around 80 and 125hz . To be honest these spike is 0.4 ms so not so high and what I hear seems very correct . So there is that if as a next step you can utilize fir/iir corrections

I see a spike in group delay of nearly 80ms. Where does 0.4ms come from?
