I've always thought that "sounds fantastic" somehow doesn't fit here. "Looks fantastic" would be better, since you can really only compare the measured curve with the target curve in the image.

Might be, I didn't test it (yet)!

Sorry, I was wrong!

The changes are saved when I press Evaluate. So your "Close" is so correct

And btw, I don't think need the next "Done screen".

The evaluation function does honour the balance setting, so it is possible to perform a measurement of just the right or just the left channel, if this is all you want.

Good idea, haven't thought of that! Thanks!

Sorry, where is the option just to Evaluate the eq / roomfit settings (I couldn't find it)? :S

Tap here and you'll find a Evaluate button at the bottom.

Thank you. Would not get there all alone Maybe just by chance

And also the EQ (PEQ/GEQ) settings, if on. Nice way to check the response if you use EQ.

If you haven't made any changes to the RoomFit profile it is expected that you get the same curve as you did at the end of profile creation.

However, some people make manual changes to RoomFit profile parameters, or add EQ on top: the "Evaluate" function then lets you see how these changes affect the in-room response.

E.g. I like to create my own room correction filters with REW and then manually load them in a RoomFit profile. The "Evaluate" function lets me easily check if the REW filters do what I intended.


There's no need to do anything. Actually, if you were happy with the sound after creating the profile, there's no need to run the new "Evaluate" function at all. However, if you made some changes to RoomFit or EQ the "Evaluate" function will allow you to see what the change did to the response.

On this note, I do hope @WiiM Team consider adding the "Individual Channel" option to the Evaluate function. It would be useful to see measurements of each channel individually post-RoomFit and post-EQ


The labels on the buttons could be a bit misleading, I agree. "Sounds Fantastic" should probably be replaced by just "Close" or something similar.

Hope this helps!

Hi @dominikz
Thx very much for your detailed reply. Helped me to understand. Much appreciated
