[Completed Beta] Room Correction for Individual Channels

[canard]

the subject seems poorly understood... but it is by far the priority for those who use the eq peq and rc modes...

known since spring 2022 from memory

this is the prerequisite for their uses... especially since in peq mode ( and the rc mode by extension) it becomes difficult to understand

Pregain for PEQ presets

As in the title - an ability to define individual pregain level for each PEQ preset, to be applied before PEQ processing.

forum.wiimhome.com

(if it is a shame that there is not the possibility of integrating the micro calibration...the discussions around the small dayton showed that in this case to put it into perspective a little)

not having the use of these modes...I got tired of pointing it out over time...



onlyoneme was right to point this out...

Of course, as mentioned earlier, it remains to be seen if this will be a beneficial option.
This is an example of usage.

With sub and crossover at 80hz.

1. Using 7 bands, run the left RC at 80hz~500hz.
2. Likewise, run the right RC from 80hz~500hz.
3. Using 3 bands, run stereo RC from 40hz~80hz.
4. Divide the gain of the stereo RC value into two equal parts and paste them into the respective PEQs for left and right.
5. Readjust the volume difference between the sub and main speakers if necessary.

What a complication I’m really lucky having not a subwoofer, and neither want it. My devices are dedicated only to music. No tv or similia. A classic stereo equipment

I think the room correction and PEQ section is a very un-WiiM mess.

If you turn room correction off, PEQ turns off. If you turn PEQ on, room correction comes on.

Only it doesn’t. As I understand it, if you’ve run room correction but turn a custom PEQ setting on, that overrides the room correction. But it’s extremely unclear.

All a bit of a mess.

Hi Steve,

Thank you for pointing that out. We'll be updating the settings related to RC and PEQ soon to make them clearer. Stay tuned for updates!

Mine is also music only, the TV is connected but rarely used. I still find a subwoofer useful.

Hi @Maurizio

I can't live without sub, but I recently ditched the big TV, big couch, floorstander in my room. From now on I will concentrate on music in this room.

And I added another sub.

You surely will face more tension between you and your neighbor by adding more bass.

It is not about more bass, it‘s about less modes!

Ps: I also use 2 subs.

In my case (and subjectivity), I found that putting two Sub's together eliminated excess sound and made the bass cleaner and tighter. The bass is quieter but denser than a my bookshelf full range. I have them under my left and right main speakers now, but they could be even better if I change the placement.

I am surprised at how much difference.

 

[MrA]

For the past 12 years I've been using very large four driver, three amp per channel open baffle speakers & twin subwoofers, digital crossovers, all ten drivers time aligned (from outdoor measurements).

I definitely could not live without subs - the system has terrific transient response with the subs contributing to tight, seamless & immense bass.

To have a sensible discussion about RC, you first need to take care of accurate and repeatable measurements. Many people have various good measuring microphones. They are certainly more accurate than microphones in phones. Once again, please add microphone calibration files.
@WiiM Support doesn't seem to have mentioned it even once and there's nothing about it in the update map either.

Have you tried it without?

 

[ArthurStereo]

Yes, I tried with an iPhone and a Dayton microphone. I do a lot of measurements and save them. The results are not very similar. But sometimes I can get a good result. I compare the results with the Housecurve app, which saves calibration files. However, I would prefer if the Wiim had this function. It would be easier and more accurate.

Using a calibration file isn't going to make the results more repeatable.

 

[ArthurStereo]

It doesn't matter. I already know how to deal with RC. The important thing is that the results are a bit more accurate and that you can change the default settings in RC. If it can be done, Wiim should strive to make their products better and more competitive.

You did say the results were inconsistent though and I have seen the same thing. The results should be repeatable so it does matter.

 

[ArthurStereo]

I repeat, for the general operation of RC it does not matter. I will write in more detail what I mean.
The results are not completely inconsistent. And in no room correction are they identical. They are similar, just not perfectly the same. You just have to take at least a few measurements, compare them and look for what repeats. The similar and repeating ones are the best, which is confirmed to me by the Housecurve app. Calibration files would make the measurements even easier. They would provide more possibilities, e.g. extending the measurement range.
And my question is, why negate the point of more accurate measurements? Is it better to have more functions in Wiim, or less? If less, then why add anything? Wiim is famous for its continuous software development and that is what I expect and respect Wiim for.

Maybe the differences with calibrated files would be minor and not worth the effort…
They certainly look for the biggest gain for the buck…

 

[ArthurStereo]

If this were the case, they wouldn't make free adjustments to frequency, max gain and max Q in RC. Without calibration over a wider range, it would be pointless.

Well then leave it pointless…
