Room Correction... I like it!

Hi, I posted this on a different stream but I am not sure it is the right one so here it is again.

I used the wiim amp, with my iphone 11 pro, to correct my room characteristics with the following result. I used a range of 30-4000Hz.

Why does the curve rise so much above 4k?
Hi AndyB,

There's something wrong with your measurement. Please try it again and see if you still have the same issue. If so, please send us a feedback ticket. We'll look at this issue immediately. Thank you for your assistance!
 
I see that Yeti X is a microphone for a computer. It is not a measuring microphone. We do not know what its exact parameters are.
Since you can use regular microphones in your phone, you can try it. You will see if it works and if you like the effect.
Just try it.
 
The Yeti X is definitely not suited to the task, even if it should work with a smartphone.

It contains 4 mic capsules, which can (and must) be configured by software for the desired directivity. Using it with a phone you could never be sure if it's in omnidirectional mode or not.
 
So, i need to find i mic to put on my iphone :/
No, you don't. You can simply use the mic built into your iPhone. It's generally considered to be about good enough for room correction within the default limits used by WiiM RC (40 Hz to 4 kHz).

You might obtain even better results with the upper frequency limit reduced to ~500 Hz. Just give it a try.

The pb is Focal Chora doesn't has big bass, so i need to correct that with Room Correction, if i set a limit to 500hz, would not be problematic ?

Room correction is primarily targeted at correcting acoustic problems caused by the room. The way this is done (by trying to match a target curve) does include some EQ of the speaker, but that's not really the main point.

500 Hz isn't even in the bass range any more, it's mid to lower midrange, so anything you would like to see corrected in the bass will still happen. You can also change the EQ created by RC to further adjust it to your needs, but this is a bit cumbersome, indeed.

Things would be a loteasier if we could have RC care for the room and then apply another level of EQ just on top of it to account for your general preferences, the music genre, your mood, bad recordings, night time listening and so on. Right now, applying GEQ or your own custom PEQ means losing the benefits of room correction. If you prefer this to change, you might upvote e.g. this feature request here:


The request has been started for the WiiM Ultra, but the same logic applies to the WiiM Amp, the WiiM Amp Pro and in fact the other WiiM devices as well.
 
Hi all, new to the Wiim Amp Pro and certainly new to EQ full stop. I've run PEQ on my Wharfedale 12.1 & it sounds certainly better than anything I've managed to get out of playing around with standard EQ, there appears to be more detail. Just wondered what you guys make of the results.

Loos good to me.

Don't worry about the big hump around 12 kHz. This is pretty much for sure an artifact caused by the microphone and it didn't influence the resulting PEQ filters.
 
It sounded ok but I switched to another album & it sounded terrible. Tinny with zero bass. My room is 10' x 12', thick carpets, tweeters at ear level. Is it worth me running the PEQ again? Any settings to tweak at all before running it? based on another post, I set to to a flat curve, 40 to 4000hz, max gain 9. No idea what any of that means 😄

Personally I'd reset all those postive values to zero.

Can't speak for Wiim room correction but on my AV pre (tonewinner AT300) it applies filters positive and negative attempt to get as flat as possible. It sounds trash. It converters a £4500 speaker into one that makes it sound worse than a £50 pair of Wharfedales.

No sub, just the speakers? If it's just the speakers there isn't anything to tweak beforehand, except for the WiiM room correction settings.

WiiM RC offers three different target curves, Flat, Harman and B&K. It looks like you selected the flat curve. Try running RC again, but with one of the other target curves, one at a time. Just see what suits you best.

Positive correction can potentially be dangerous if the processor tries to fill holes in the frequency response, which are not correctable, because they are caused by room modes and resulting cancellation. I would have hoped that the most recent implementation of WiiM RC would attempt to detect these cases, but taking a closer look at your measurements this night not be the case (or at least not 100% reliably).

Search for those frequencies where a positive gain is applied by room EQ, but the resulting curve isn't any higher then the measured curve. This might be a problem with the 96 Hz PEQ, indeed. Did you take a screenshot of the final assessment, too?

Generally speaking I see nothing wrong with positive gain corrections.

I think once you’re accustomed to bass and mid bump and rc flatten those would result in tin sound. Flat response you loose bass thump just flat bass.

If you have become used to a 9dB boost at 62Hz then removing it will sound bass light. Which album sounded OK and which one sounded terrible?
