PEQ: Graph should reflect Q value for shelf filters

[harkpabst]

The PEQ feature in WiiM's products has developed very well over time and definitely turned into an extremely powerful tool. One great feature is the support of fully flexible filter Q values, not only for peak filters, but also for high shelf and low shelf filters.

Unfortunately, the effects of different Q values are currently displayed for peak filters, only.

For example, here are the graphs for a 200 Hz +10 dB PK filter with either Q=1.5 or Q=0.15. The difference is obvious and understood very intuitively.





In contrast, the graphs for a 200 Hz +10 dB LS filter currently look exactly the same for Q=1.5 and Q=0.15. But this is not what really happens.





My request is to visually display the effect of different Q values for shelving filters as well.

For the LS filters shown above this should look somewhat like this:




Although I am well aware of the fact that precise measurements should ideally be combined with listening experience, this would be a more than welcome improvement.

before stacking functions see enough annex.. it is good to make the current ones see essential "finished"
no?

I partially agree.

More to the point, I think that if thay have completed enough discussions (with specialists or users) in the early stages of developing new features, thay can create something that is highly complete from the start.

we could hope that they have enough internal skills on these audio subjects, rather basic-classic, ( like cal for microphone, latency problems, rc methodology, subwoofer management,etc etc) to not need feedback for developments upstream...

in any case since the creation (07/22?) of this forum I have not come across a wiim interlocutor having this type of skills to be able to dialogue, answer our questions, explain their difficulties, delay, on these subjects...

waste of time for all
