WiiM Home App v3.0.5 Update - Dec 11, 2024

[slartibartfast]

Actually I think the explanation is pretty clear:

Smoothing: In Room Correction, smoothing reduces small fluctuations in the frequency response curve, making it easier to interpret and focus on overall trends. It removes unnecessary details caused by noise or measurement artifacts, prevents overcompensation during adjustments, and helps achieve a more natural correction outcome.

So, 1/3 smooting is the strongest, 1/12 the weakest smoothing. Which means 1/3 corrects maybe too much, 1/12 might correct too little.

Nobody has the answer to what is best for your room, as every room is different.
It‘ll be trial and error.
The default value is certainly a good point to start…

I would have thought it might correct too little with 1/3 octave smoothing because a lot of the higher peaks and lower troughs are reduced. So correction is also reduced.

Ryan's explanation is clear, but I think the people who can understand this are those who already know PEQ.

I think a more practical (with images or videos) explanation and use cases would reduce misinterpretations and questions. This is true for functions other than RC and PEQ as well.

However, it is a difficult question how much WiiM should teach in a helpful manner.

Audio Science Review were going to do a tutorial for room correction a long time ago. The first article was produced and then nothing else appeared. The REW website has links to many YouTube tutorials on room correction.

It would be helpful to simply post a similar link to the WiiM FAQ or Tech Tuesday.

Can you please post the link here?

It mainly refers to REW but the same basic principles apply.

Interesting, but it also shows, how fast it get‘s really complicated and theoretical!
Personally I prefer a pragmatical practical way, and it seams to me WiiM does exactly that!

 

[canard]

just for idee for type, precision, of smoothing at 1/3 octaves full band ....
or 1/6
etc


just variable but in multi measures would be much preferable....

Luckily it is easy to try different settings until you find what works best. In my case I boosted the sub by 15dB so all the low frequency corrections are cuts. I also limit the frequency range to 30-400Hz.

Not the actual correction but the chance of over correcting. I'm not yielding on this.
In Wiim for auto RC we set a maximum frequency span, max dB (Max and min should be separate btw,@WiiM Team. Max +4 dB should do nicely for rc, -10 dB is fine) for correction and max Q.

remains the absence in all cases of auto gain... and intelligent if an l/r mode...


What approach does housecurve ( which remains the dedicated application, inexpensive, and with a certain perspective on this subject...) use?

HouseCurve provides a range from No Smoothing through 1/24th to One Octave of Smoothing, It’s not automated, you choose. The typical approach is use say 1/24 or 1/12th for Lower Frequencies e.g 20-200Hz and apply PEQ 5-6 filters and then a second pass with 1/6 at 200 to 500/1K/4k for another say 4 filters. Every room is different so there is no ideal answer for everyone, it’s a case of trying until it sounds good for you.

What is the cost of housecurve again?
(for a long time the essential thing is that wiim can offer a high-performance peq (to see one day maybe expert mode with fir)... after the rc approach is a vast subject... if it was simple it would be known and would have been generalized for a long time ;-) )

I think it was around GBP 10 when i got it a while back. Excellent value for money

Got a new Android update today 3.0.6 and still no sign of smoothing options for room correction.

 

[faustocat]

Here in Italy updated to 3.0.5 and still no sign of smothing option

 

[slartibartfast]

For those interested smoothing will "likely" be included in next week's Android app update. Just in time for Christmas

I've had a Wiim Ultra for 2 weeks after owning the mini for 2 years. Since the update, this is the second time I've been unable to log in to Tidal. But it works on the mini ????

Reboot/power cycle the Ultra, and clear the WiiM app cache if you’re on Android, or delete/re-install the app on iOS. If the issue persists, raise a ticket to WiiM thru the app more/feedback section.

A restart via the app solved the problem.
