There is no right or wrong here, just preferences. With my speakers, the Harman curve produces too much bass at the very low end, so I used the B&K and have not had a need to modify it further,
May I edit the correction curve, the purple one?
You edit the yellow one, the target. the purple correction curve is the resulting difference between the saved grey measurement and the yellow target. You can’t edit that.
You can edit the correction properties, like the frequency range and the max. dB correction. But anyways, don’t overcorrect to try and force everything onto a straight line, it can make things worse.

Thank you for answer. I would like not bump up, but only or prevalently down
You do that by moving the yellow target curve so that it is largely below the grey measurement average.
Maybe I wasn’t clear. I would like to modify the correction curve so as to leave intact the parts where the curve goes down and almost cancel out the parts where it goes up.
Yes that’s what it does if you move the target curve further down. Just try it out at several different levels 
You can also use the Equalize Tool if you want to change the influence at particular frequencies.
(You can try different corrections for one set of measurements, no need to re-measure)

Yes. Allow only cuts was what i was looking for. Thanks

I came across this topic by chance. I downloaded the software immediately. These instructions for the implementation in Roon helped me a lot: Link: houscurve.com - Step by Step Roon Manual
Now I have measured various rooms according to these instructions and have been able to correct them accordingly. There are various HomePod Mini in my house. In the living room is my main system Yamaha S701, Eversolo DMP-A6 with B&W 603 floorstanding speakers. I am really surprised at the improved playback quality. They are rather subtle here.
The biggest difference was in the bathroom. The sound there was rather muffled and too bass-heavy. Corrected, the sound is now much more pleasant. Really amazing!
Thank you very much for this valuable tip. I am thrilled.

If I use left and right and averadge the result is only one FIR file that I load into Roon or I can Loading more file into Roon?
Then, is there a way to measuring with HouseCurve and edit with REW?
This app is fantastic. Really amazing results with my first tests.
I am using it with Roon in a kitchen, dining room with in ceiling speakers… four of them.
What would the best way to measure be? People walk and stand kinda close to the ceiling speakers in the kitchen (only 3 feet above ear level), and then there are some lower bar stools, and finally some lower chairs at the dining table. Would it be a good idea to take measurements at all of these heights? Or just one height?
You’ll have to experiment. In my kitchen, I found measuring one area worked better than trying to average it all. I chose the bar area as the “main listening area”, measured ~5 locations at ear height. The bar area obviously sounds the best, but the rest of the kitchen sounds fine.

I just updated to ios18 and a bit of fun getting the app to work with my Umik 1. All working now though.

Hi everybody,
I started experimenting with this app.
I selected the only cuts option to avoid clipping.
It’s also written “ It is best to also lower the target curve a few decibels to get a better correction”.
Now what’s a few dB? 2-3? 5-8? 10-12?
That’s for you to decide, maybe the following will help…
few
(fyo͞o)
adj. few·er, few·est
1. Amounting to or consisting of a small number:
2. Being more than one but indefinitely small in number:
n. (used with a pl. verb)
1. An indefinitely small number of persons or things:
Well…
The target curve can be lowered in different ways. It can be baked into the curve or you can use the headroom feature of Roon. Lowering the curve is the same as apply a reduction in amplitude in the digital domain - which is what adding headroom does.
Either way, it is used to prevent numeric overflows from happening when the curve is applied resulting in digital clipping (or even worse, wraparound). In principle, an ‘only cuts’ curve should not need to be lowered further.
Personally, I would not lower the curve generated. Instead I would use the headroom setting in MUSE. If you do this you can start at 0dB (no lowering) and enable the clipping indicator like:
Then you can monitor the clipping indicator (the stream quality indicator goes red if clipping occurs) and if clipping is seen, then you can add more headroom by applying increasing negative dB’s to the Headroom adjustment until you don’t get any clipping.
Note: Whether or not you see clipping may depend in part of the amount of headroom present in the digital file. Thus, you may have to revisit this several times as you play different music.
Alternatively I believe that there are some sample full scale ‘chirp’ (single tone varying continuously in pitch) files that can be used to expose any digital clipping. Using one of these and adjusting the headroom until no clipping occurs will give the true value required first time.
Tks that’s very useful.
My issue is this that I have 2 big dips at around 42 and 77 Hz
If I leave the curve in auto it’s at -21.4 dB then the equalized results with cuts only is like this
Still have -12.5 dB at 75 Hz
Now if I lower the curve at, let’s say -30 dB for instance, the results is like this:
Only -3.1 dB at 75 Hz
The rest of both curves look pretty similar except above 10 KHz, not sure at all my earring is still good enough to ear those very high frequencies.
So, if I’m using the auto fit curve and Roon headroom I’ll still have my dip at 75 Hz and I might add some negative dB to headroom due to possible clipping.
On the other hand if I’m using the -30 db (or something between -22 and -30) the results looks better (obviously I have to listen to it) my dip is smaller, the rest of the curve pretty similar till 10 KHz, I just have to push the volume of my amp a bit higher to obtain the same volume.
Is this wrong thinking?
Actually, your second curve starts rising from 4kHz onwards.
I’d change settings to better conform to the target.
Other than that, if you’ve got enough gain to make up for the lower target, go for it.
