How are my graphs? And some filter help.

[Joffieb]

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

Nothing?

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.

Thank you, mdat file attached.

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.

I remeasured. Please see here:

Measure stereo channels separately or together to create filters

Hi All, I looked into the question whether to do a combined measurement and create filters or do separate measurements for right and left and create separate filters for each channel. The opinions online were varied with most people on the side of separate measurements. I felt that the opposite...
