It works as advertised. It won’t probably stay on beta for long time. I’m wondering if they plan to release more than 10 band and separate eq for subwoofer.

It seems to me that this time @WiiM Team decided to complicate our lives. As things stand, it's a big mess and I don't understand it.
1) With the separate RC do I lose my sound profiles previously saved with the Automatic RC? This would be very bad. It took me a long time to perfect them
2) If I understand correctly, according to @kjell.bjornfors There are no longer any curves obtained, where I can check the results graphically. Is this true?
3)
This separation seems to me to be a mess. Wasn't it sufficient, and better, to leave everything as it was with the added possibility of superimposing a GEQ profile on the PEQ, as requested by many of us?
Simpler, more immediate in use and without the risk of losing what was done before.
Instead of this unnecessary separation, it would be better to put resources into more useful things, such as more adjustable frequencies. 20 instead of 10.
House Curve provides for the use of up to 20 frequencies. How many to use depends on the user. From a minimum to a maximum. Like Gain or Q

Hi Maurizio,

Thank you very much for your feedback.

#1 You will not lose your sound profiles after separating RC from EQ. You can choose one of them for RC. In the meantime, we will introduce support for editing sound profiles this week.
#2 Following point #1, we will also support evaluating the sound profile after editing.
#3 Regarding the 20-frequency upgrade, we have already investigated the matter and are continuing to optimize CPU and memory usage to support it.

@WiiM Team Do you plan to make this feature available to the rest of WiiM products such as Pro, Pro+, Amp, Amp Pro?

Thank you very much for answering me. I would say that you have clarified some of my doubts.
Let's see what will come out of this separation between RC and EQ. I am curious to see the final version. I hope it is easy to use and intuitive, not all of us are sound engineers.
In this regard, and to conclude, I have a small suggestion. When we will have the final and official version, it would be useful if you made available a small and simple step-by-step guide on how to use this new RC and EQ seoarate, with particular attention to editing; copying; importing profiles
Thanks again

I agree with you. Using PEQ for additional EQ effects seems counterintuitive to me . As you say, PEQ is not really easy to use. To add or refine the sound at will, GEQ is much better, especially with presets. Jazz; acoustic; treble and so on

 

[Gerry_Tang]

I think one of the best use of this new feature is adopting a graphic EQ such as loudness (e.g. low volume listenings) while still benefiting from the great convenience of RC. So i really hope this feature will be implemented in an user friendly manner

I'd say some (probably few) might use the additional PEQ to implement loudspeaker correction based on anechoic data, and some might just use the high-shelf/low-shelf filters as treble/bass controls.
IMHO it doesn't hurt to have both GEQ and PEQ available, given that the framework has already been developed. Having both available extends the possible use-cases a bit.

But the main use-case for EQ on top of RC should be to easily tune the overall tonality to taste (or to a specific recording) - for this a simple tone control that changes overall balance from "warm" to "bright" would do, or alternatively separate "bass" and "treble" controls could be implemented. This would be much simpler to use than both GEQ or PEQ.

This would probably be a much more intuitive solution for tonality tuning for most users so I wonder whether @WiiM Team are already considering it?

While some have suggested tying RC and EQ to specific inputs/outputs, we believe it's more effective to keep them separate - RC for acoustic optimization and EQ for personal adjustment.

IMHO that is absolutely the right approach. Now the main thing to do is to fine-tune it from ease-of-use / ergonomics perspective.

After that, we will support importing AutoEQ profiles for headphone output, either from the AutoEQ database or via manual input.

This is really good to hear! Will you support the same functionality on the BT output (i.e. to use with BT headphones)?

Also, given that you mentioned some plans to potentially introduce more than 10 bands of PEQ, have you thought about introducing similar integration with spinorama.org automatic EQ profiles for loudspeaker correction based on anechoic data?
This could work together with RC to facilitate optimal full range correction (e.g. RC below 400Hz and the appropriate spinorama.org auto EQ above 400Hz). I suggested this before here.

As for editing Room Correction results (Edit, Import, Delete), these features will be implemented this week or next, and a new beta version of the app will be released. We will also support importing profiles into Room Correction.

That sounds very promising!
Does that mean that it will be possible to import EQ configs from e.g. REW to use as RC profiles?
Will it also be possible to export WiiM PEQ/GEQ/RC profiles to a file?

 

[Wiimer]

I think the whole point is to separate EQ and RC so they can be managed separately.

I agree that probably for most people there is no need to add PEQ to the RC, but it is possible to turn off the RC and use only PEQ. That is still possible today, but could not be managed separately. (Maybe it needed to be separated from EQ to allow RC profiles to be viewed, edited and imported).

According to the team, when using headphones, RC is turned off and only PEQ for headphones is available. Then, when you switch back to speaker output, RC should automatically turn on and you should be able to turn off PEQ and apply your preferred GEQ. This would be a great advantage for headphone users .

It would already be welcome if the peq mode display corresponded to a mathematical reality...
or even to be able to switch it to landscape mode to be more readable and precise if its relevance ends up coming....

(and one day without rc mode, just a raw but precise display chirp measurement mode, to simply observe the results of our peq etc!
,-)

(The variable loudness option like the old Yamahas would certainly remain very practical( often used for low-level nighttime listening ) for many if accessible on the main page under the level...often pointed out as an idea ..but a num var loudness almost necessarily requires an...autogain ;-)
could be in place (here fixed level so not used) or under this level cursor... )

@WiiM Team, @WiiM Support,

Are there any plans to allow import of EQ (or RC) profiles for the USB output as well as the headphone output?

This would allow dedicated EQ to be applied to wired headphones via USB DAC or Bluetooth headphones via USB BT adapter.

Thank you.

Hi Wiimer, Team

Our team is currently evaluating this - thank you so much for sharing your insight on the feature. We truly appreciate your input!

I think i depends on how many filters you have in RC. If all are used in the low frequency span and there is some problem left higher up it could be usefull. Untill now I have used one filter to compensate problems I have with my Carlsson speakers mid/high filter. My RC works below 400Hz.

@WiiM Team , @WiiM Support

Do you plan to add low pass filter and high pass filter in the additional EQ setting?

Thanks,

Hi jed1,

Yes, we can support LP and HP in the EQ settings this month; please stay tuned!

To me this is all very good news. @Maurizio, I'm sure you will love the final implementation. As of now this is still a beta release, so we all should expect minor bugs and an initial lack of full functionality. This is the agile way WiiM are implementing new features: Start with an MVP (Minimum Viable Product), adding instant value, then develop it to full fidelity, step by step.

 

[Maurizio]

Hi @harkpabst
Yes. I want to be confident and think that I will really like the final version.. You see, I'm a newbie when it comes to EQ in general and RC. I've just started to take my first steps with ARC with WiiM, and at this point I think I've gotten some good results. However, I'm far from an expert in this field and some new things scare me, making me feel like things are getting too complicated. I tried looking into REW, but it's far too complex for me. Headache stuff. So I'm grateful to WiiM for making a feature like RC accessible to even the most clueless.
Now we are talking about High Pass and Low Pass filters. For this reason I believe that, when everything is ready, a nice step by step guide on how to use the various functions will be of great help if not to everyone, to many for sure.
In my ignorance, however, I agree with @slartibartfast that PEQ is far too complex to be used to refine the sound at will. On my opinion a graphic EQ is much better for this purpose.
I also agree with you that WiiM is commendable in always adding new features and continually improving existing ones. I think they are one of a kind. Congrats.
Taking inspiration from House Curve, another change that could be made by WiiM concerns the choice of filters. In WiiM Automatic RC all filters are PK. In House Curve the program chooses if and when it is best to also use the HS and LS filters automatically.
