Seeking Your Help: Share Your EQ Files to Improve Our EQ Import Feature!

[WiiM Team]

Hi everyone,

We’re currently developing EQ Import for WiiM devices, supporting formats such as REW EQ files and AutoEQ configurations.
To make this feature compatible with as many real-world use cases as possible, we’d love your help.

What We’re Looking For​

If you have used:

• REW exported EQ files (e.g., TXT format, Filter Export files)
• AutoEQ-generated EQ settings (e.g., Parametric EQ files, CSV/TXT outputs)
• Any custom EQ configuration files you normally use

We would greatly appreciate it if you could share a few sample files with us.

How You Can Help​

Please upload your EQ files (any formats you usually use) in this post or send them to support@wiimhome.com.
The more samples we can study, the more accurate and user-friendly the EQ import feature will be for everyone.

Privacy Note​

All files will only be used internally for analyzing format structures and ensuring compatibility.
No personal information is required or stored.

Thank You​

Your contributions will directly help us build a more powerful and flexible EQ system — especially for advanced users who rely on REW or AutoEQ for fine-tuned listening.

We truly appreciate your support!

Amazing, thanks so much! I'm very exited about this feature!

@WiiM Team May I ask a few questions related to this upcoming feature?

1. Will the PEQ file import work in RoomFit as well, or only in EQ? Ideally it would be available in both functions...
2. Will it be possible to import separate PEQ files for left and right channels when using "L/R" PEQ mode?
3. Are there any plans to also implement PEQ filter export to file from RoomFit and EQ?
4. Have you considered contacting John Mulcahy (the author of REW) to add the WiiM PEQ type specification to REW "Equalizer Panel" (link)? This would make it significantly easier to create filters compatible with WiiM SW in REW.
5. Being able to push the PEQ config to a selected channel of EQ or RoomFit on the desired WiiM device directly from REW via HTTP API would be ideal, of course...

Please find attached several REW generated EQ file examples in a few different export formats. Note that some examples use configurations which are intentionally out of the ranges allowed by WiiM PEQ function - perhaps these might be helpful for testing of irregular input.

In addition, here's a few links to loudspeaker correction PEQ presets generated by spinorama.org (many more are available there):

• Fluid Audio C35BT PEQ filters
• KEF Muo PEQ filters
• TAD COMPACT REFERENCE ONE CR1TX PEQ filters

Note that these also include recommended preamp gain value (i.e. to avoid overload in fixed-volume-output cases).

This is a great development, i look forward to using it !

 

[canard]

It's been expected for a long time... but not "an emergency" since it can be just entered manually.
It's "accessory".(And honestly...it will only concern a few people)
(It's important to make a clear intellectual distinction between... what concerns room correction... and just raw data like Spinorama's speaker curve etc)

I understand the request...
but frankly, when you open your file, you realize it's just a few numbers to enter (max 30)... maybe double if l/r (max 60)...

when we see essential things left unfinished, forgotten, etc.

Hi @dominikz ,

Please check our replies below. We will introduce these enhancements in stages to ensure quality and stability:

1. PEQ import will be supported in both RoomFit and EQ.
   This will be part of our first implementation phase, so users can bring their own PEQ files into both features consistently.
2. Importing separate left/right PEQ files in L/R mode is a great suggestion.
   This requires additional UI and processing logic.
   We plan to include this in a later phase after the basic import/export framework is completed.
3. PEQ import and export will be supported for both RoomFit and EQ.
   
   • Import will be available in the first phase.
   • Export will follow in a second phase, allowing users to back up or share their filter settings across devices.
4. We haven’t contacted John Mulcahy before, but we will now.
   Adding a WiiM PEQ profile to REW’s Equalizer Panel will make filter creation easier for everyone.
   This collaboration will be part of a separate integration phase, depending on REW’s development timeline.
5. Directly pushing PEQ to a selected channel via REW (HTTP API) is something we will evaluate.
   We need to understand the workflow and technical requirements first.
   If feasible, this would likely be introduced in a future advanced phase, after import/export and REW compatibility are established.

Thanks so much for the detailed response! It's great to hear a lot of it was already on your radar.
With these features we will be able to backup and restore EQ and RoomFit profiles much more easily, which is IMHO a very important capability.

Regarding item 2. on the list, does this mean that import/export will initially only work with "stereo" type EQ/RoomFit profiles and won't work at all if "L/R" type is selected in WHA? Or it will still work from the start, but with some limitations?

I agree that the feature under 5. is the least important, but it's still nice to see you will consider it for the future! I suspect a lot of the development needed would be on REW side, however.

 

[canard]

In summary... point 4 is the effective one... but the work on the side..but, if he accepts it , the job is for mr mulcahy in his rew...

Probably a stupid question, but I will ask anyway.

Many devices have an option to change Bass / Treble from -5 to +5. When we do that, we see that the device automatically applies some correction to the frequency response - not to the very specific hz but basically to the entire region (bass or treble).

When I use Graphic EQ, am I changing only specific hz: 31, 63, 125, 250 etc, or entire regions between those Hz - from 31 to 250 (or even a bit before and after these Hz)

And the second question. Can we get "loudness" that would change automatically in relation to the volume level?

I don't know why bunt when I was using Bass or Treble +0 to +5 with Emotiva preamp, it sounded better than when I tried to do the same thing with Wiim Ultra

I fully agree that it would be great to have a simple bass/treble (or just a single tone tilt) control in the WiiM Home App - that would make it much simpler to adjust tonality on the fly.

For now you can make use of the PEQ shelf filters to do the same thing - though it is not as intuitive.

Here's how to do that:

1. Open the WiiM Home App
2. Select your WiiM device
3. Tap on the gear icon
4. Go to the EQ menu
5. Choose PEQ Mode: Stereo
   • Bass Control (low-shelf):
     • Filter=LS
     • Freq=100Hz
     • Gain=according to your preference
     • Q=0.70
   • Treble Control (high-shelf):
     • Filter=HS
     • Freq=4000Hz
     • Gain=according to your preference
     • Q=0.70

Example of how this might look for the Bass Control set with -3dB gain:

You can then save a few PEQ profiles with different gain values, and then assign them to Presets in the WiiM Home app - that gives you the ability to change Bass/Treble balance by press of a button (you can change presets from the remote, or from the WiiM Home app).

E.g. you could have Preset 1 with EQ disabled, Preset 2 with +3dB bass, Preset 3 with -3dB bass , Preset 4 with -1dB treble, etc..

Hope this helps!

Thank you Dominik. I know I have a PEQ for this. I was only wondering how EQ works. So it seems that it indeed applies correction only for the very specific Hz, right?

I just discovered that I can move my finger on the screen on PEQ and change the gain without entering the values manually! It changes a lot. The only manual entry that needs to be done is for the "Q" value.

I fully agree that it would be great to have a simple bass/treble

Yep

 

[dominikz]

Thank you Dominik.

No problem!

Well that depends on which filter type you choose.

If you use the values I proposed in my previous post then the bass control ("LS" is low-shelf) will affect all frequencies below 100Hz, and the treble control ("HS" is high-shelf) will affect all of the frequencies above 4kHz.
If you use the default "PK" type (i.e. peaking) then the EQ will only apply on the frequencies surrounding the chosen frequency - that is not ideal for this use-case.

Devices which have bass and treble controls usually also have them implemented as PEQ shelving controls - though not all vendors use the exact same values for the frequency (so you may wish to adapt that).

 

[harkpabst]

Have you considered contacting John Mulcahy (the author of REW) to add the WiiM PEQ type specification to REW "Equalizer Panel" (link)? This would make it significantly easier to create filters compatible with WiiM SW in REW.

I had missed this so far and must say it's probably the best suggestion in the history of WiiM!

 

[Fletcher Munson]

This is great news, i look forward to the feature. can we also export PEQ settings FROM wiim please as well, so we can use them across devices

 

[Fletcher Munson]

IMO the roomfit and PEQ is why i'm in the Wiim ecosystem, Wiim pro and pro plus owner. very happy with both

Can you sell a low cost calibrated mic as well

 

[Mr Ee]

And the second question. Can we get "loudness" that would change automatically in relation to the volume level?

The wiim Sound has Dynamic Bass.
Maybe it'll come to other devices too? Can't see why it would have to be specific to their speakers.
