A New Harman Target for 2024??
Dr. Sean Olive of Harman International gives a presentation at CanJam NYC 2024 detailing his preliminary work on adapting the Harman target to the new B&K 5128 measurement standard. In this presentation, Dr. Olive covers how the Harman in-room baseline compares to the diffuse field HRTF, what a beta curve on the 5128 looks like, initial testing of Harman IE and other in-ear alternatives, along with new audio research that's being done.

Thanks for the update - can you confirm if room correction uses an external mic (like the Drayton IMM-6) if present and whether you’ll add a feature to import mic calibration data?

Which models will this be for? Amp, Pro Plus and Pro? Or also the Mini?

Is that your bass issue fixed?
You always have the option not to use it?
Does it allow you to save on each individual curve? Let say flat then switch to Harman without running calibration just for Harman.

Not that I can see
Is it possible to have 3 different room correction performed and switch from one another to compare? Thanks!

Fwiw, Sonos introduced their auto-room correction “Trueplay” in 2015, and still have not adapted it to work on Android – even though many Sonos users have publicly suggested over the years that an external mic could address the claimed microphone inconsistencies of Android products. To add insult to injury for Android users, Sonos' official support advice is "Borrow an IOS device from a friend". Hopefully Wiim can succeed where Sonos (apparently) fears to tread.

I notice that the HouseCurve developer has said in response to many requests for an android version that he’s just a “sole dev” and that there’s only so much time he has at weekends, not that it’s not technically feasible (unless he hasn’t had time to investigate it in any depth). So maybe WiiM can pull something out of the hat if users do invest in an external mic.

Seems to have gone a bit quiet here - what’s the general opinion apart from some aforementioned omissions and potential future features? I haven’t had a great deal of time to play with it but for the features delivered in the second beta, it’s looking very promising.

I've used it a bit and noticed that the room correction seems to only apply to the Wifi input. i use the optical input as well to use my tv and it doesnt seem to apply there. I've tried to use the room correction while on the optical input put it applies to the wifi input anyways. Does it only apply to wifi or is there a bug?

I wonder if it’s clashing with the other feature of input specific EQ. I’d bug report it tbh

I haven’t looked that closely tbh since almost all my usage is wifi input, not external

i see. will report the bug anyways and hope its just a detail and i hope there will be a better way to see the filters in the eq tab aswell.
Dear WiiM-team,
concerning mic calibration of apple products, I get quite different results in a device room correction app (for a nubert subwoofer) by using different apple mobile devices (Iphone, 2xIpad). So I would expect not too much from the DRC results compared to an external calibrated mic + soundcard system.
To include some value for Android users you may not correct these according to an (absolute) target curve, but focuse relatively on unhealthy peaks within a small frequency range (e.g. frame within 1/5 of an octave, limited to the main hearing up to e.g. 8000Hz).
To overcome mic calibration flaws or to adapt individual likings you could allow creating a user target, based on e.g. a custom EQ (which is already implemented the app).
It seems that the correction starts at 50Hz. In my room, the first basic mode is at 17Hz (so also 34Hz), the second is also under 50Hz. Could you therefore make a further selection field to choose the number of PEQs which are used for the automatic room correction function.
I'm looking forward to seeing the new features implemented. Thank you!

for there to be resonance... the frequency must be requested... (and moreover proportionally to the level) thinking "0db" misses a basic and essential thing (same with high frequencies)
Many words etc end up completely ignoring what is the nature of what we are listening to....
(without mentioning here the wavelength of 17hz 20m or 34hz 10m ;-) )
