Hi All,

I am attaching five images, a green graph as my room unfiltered, an orange one with filters applied in my Wiim Mini and a comparison one with both showing and the room curve a spectrogram of the raw room and one of the flirted room.

My first question is, how do they look?

Also, as there is no preset for Wiim in the EQ settings, what setting should I use to set up the EQ? Wiim can do four filters but I don't know which options to choose for Gain Range, Q/BW format and range.

Please can I have your input. Thanks you so much

Yes. Attach mdat file. Then it will be possible to say more. According to the pictures, there was a 20 dB difference between the peak at the bottom and the peak at the top. It remains that way. The middle has smoothed out a bit. There is a 20 dB difference between bass and treble. It's too big of a difference.

You are playing back recorded files. When you created them, you specified LR_ref_L. In this case, two channels are played simultaneously. If the microphone is not exactly in the middle between L and R, one signal overlaps the other, and you only see one graph. This is not happening correctly. As a result, you may see false information. It is better to measure one channel at a time. When writing a file, specify L_ref_L and R_ref_L. After measuring, the graphs can be folded into REW if you need it. Therefore, the measurements taken again do not provide the necessary information.
