Room correction

[Yoku-San]

Dear @WiiM Team,

can you share anything about the room correction feature you are supposedly working on?

Thanks for information in advance!

 

[harkpabst]

Yep, easy to get confused with so many feature requests and comments in so many different sub-forums, all concerning similar topics.

AVRs usually try to measure the distance to different speakers automatically, but the results are often mediocre, at best. Entering distance values from the MLP to the speakers looks like the most versatile option to me. It's easy enough to do for the average user and still gives full flexibility for those using their own measuring equipment anyway.

So, a quick question for @WiiM Support .

Room correction: will it include delay/distance, or just frequency, level and polarity?

 

[Navdak1]

Just crazy idea)) To do a room correction using AI. We get the frequency response of the room with mic for WiiM, then the AI analyzes deviations of the room based on the resulting graph and suggests making changes to align the frequency response based on data with a flat frequency response. I mean, we simply show our room frequency response, and the AI adjusts the graph data based on a flat frequency response. You don't need any programs and an understanding of how to do it. Because I started to study this question, but everything is very confusing

My Onkyo AVR has never returned a satisfactory result. The center channel is low volume, and the sub is too much volume. I can't see why anyone needs it for stereo. Use your ears. You will probably end up using them anyways.

My Lyngdorf amplifier pretty much always returns a satisfactory result. No center, perfect sub integration. I can't seen why anyone wouldn't want the same from the WiiM Amp at a fraction of the cost.

Room correction by ear is simply impossible. You can use the extensive tone controls to accommodate your taste, anyway. Just don't claim you "improved" in-room response by doing so.

I hope that WiiM allows the use of a Umik with their calibration software when it's available.

The Umik-1 (and Umik-2) are the most widely used in home audio calibration. There are certainly other options, but if you look around all the audio forums, from home theatre to hifi, people are using Umiks because they are not too expensive, come with calibration, and run with just a USB connection (no mic preamp or separate power).

If WiiM try to enable calibration using smartphone mics, they will likely run into the issues that Buchardt has encountered: too many different phones with too many different mics that are not well suited to measuring frequency sweeps accurately.

HouseCurve is iPhone only, as they find that iPhones are consistent with their mics, so the can build in the typical inaccuracy from flat fq. They also allow for use with UMIK and others.

@WiiM Support, can you tell us the progress on this feature? Thanks!

This topic of room correction became silent.

Hi Team,

Thank you for your continued patience regarding the development of the room correction feature and the 10-band Parametric Equalizer (PEQ). Our team is diligently working on these enhancements. We are excited to announce that we aim to release the Beta version in the upcoming two weeks. Please stay tuned!

Do you mean 8 band PEQ as shown n your roadmap?

 

[harkpabst]

Too bad, it's been upgraded to 10 band PEQ.

TEN BAND!?

I hope that’s not a typo, the more the merrier.

And that’s smashing news, thanks for keeping us updated.

 

[canard]

if the application can consider left and right separately , 2* 8 , would be a real plus...

 

[Smartplug]

Peq with more band is needed for room correction to be more accurate. 10 band sounds good to my ear which they only stated 8 on their roadmap.

Why you need separate on left and right unless you put your speakers on unusual setup?

 

[harkpabst]

Because few people have a "usual setup".

Real world rooms feature annoyances like windows, doors, asymmetrical shapes, coffee tables and curtains arranged by the wife (not the HiFi dealer).

 

[canard]

indeed the answer is in the question...
;-)
I'm not too concerned but it's a very common problem...
which surprises me but it's a global subject that we can observe..
it's to point out ever more exact needs for functions concerning audio, without talking too much about the quality of these...

here at what resolution is this peq mode? etc... somes technicals informations?

there is a certain irony in having observed for months the requirement for "hd" 96k :thdg streaming 192k ", "mqa", "absolute bit perfect"...

to now put all that ""under the rug""...

;-)))

 

[harkpabst]

I care about room correction roughly 256,672 times more than about HD or bit perfect or Hi-res and 192 kbps.

Double that number regarding bankrupt MQA.

I'm not even talking about an auto correction mode which is quite a subject in itself..hihi...

just "simple" peq here... ;-)
