Ongoing Beta Beta Testing: Independent L/R Room Correction with Subwoofer

I think the Harman filter was generated using the previous beta L/R algorithm and the B&K was with the new algorithm.

At first glance the filters look like we should be seeing a significant difference around 20Hz (which we do) and about 3-5 dB difference between 150Hz and 250Hz (which we don't).
I assume this is the combined L+R measurement in both cases, right?
Do you by any chance have individual channel measurements in REW? To compare just the left channel response with B&K vs Harman filters loaded? Since the filters were calculated per-channel that might be informative.
 
I performed two more room corrections. One Harman and one B&K. After saving saving them as Custom EQs and measuring again the results have changed again. The Blue and Green curves at the bottom are both B&K, one of them is the same EQ that previously looked like Harman. The Orange curve is a Harman generated with the old algorithm and the Red curve is Harman generated by the new algorithm. The new Harman curve is 2-3dB higher than the old one at low frequencies.
So somehow the act of generating new Custom EQs has corrected the way the other saved EQs perform.

Good to see that now at least it seems to work as expected! Still probably worth opening a ticket regarding the issue you saw before.

BTW I personally wasn't able to reproduce the issue you had, sorry - running the new RC with different target curves provides the expected results, and my older manual individual channel PEQ presets seems to be loaded correctly as well:

Perhaps it is because in the last days I already used the new RC a few times for testing? No way to be sure...

I did open a ticket earlier. Mine was working yesterday morning, I posted in this thread showing the difference between the old and new B&K results. Somehow it stopped working later 🤷‍♂️
 
Filled out the Google form but don’t seem to have this feature on my latest version of the app.
 
Hello gentlemen! Just wanted to check if there are any news about this feature being released? In my case individual L/R RC seems to sound much better but I want to use it with my sub. For now, I am listening without any filters hoping for this to be released soon…)

How much time did you give them? I'm pretty sure that this is a manual process. Did you double check you did provide the correct MAC address(es) of your device (not the AP MAC address)?

Hi dominikz,

Thank you for your suggestions. I’ll review these Max Gain control improvements with our engineering team and aim to implement them promptly.

@WiiM Team Have you perhaps had any chance to look into this topic so far, and do you have any updates you could share? Thanks a lot!
