No, just read theory please. LP and HP filters in Wiim are without Gain regulation, so you cann't adjust slope of the cut. Did you try it on WiiM ?
You keep using wrong or misleading terminology so it's very hard to follow your thoughts.
By definition high pass and low pass filters do
not have gain. Some platforms might combine filter settings with gain but that's a different matter. I'm not even sure if you really mean gain when you say it. Gain has
nothing to do with the slope.
High-pass filters typically have a cutoff frequency of -6, -12, -18, or -24 decibels per octave ("dB/oct").
That's the
slope of the filter, defined by its order, not its
cut-off frequency. A frequency is given in Hz, not dB/oct.
A low-pass filter is often also called a high-pass filter, since it cuts off high frequencies.
No, a low pass filter is
never called a high pass filter and a high pass filter is never called a low pass filter. Both are doing the exact opposite thing. If you meant to say that a low pass filter can be called a high cut filter that wouldn't have been wrong, just less common.
High and low pass filters are exactly defined by their cut-off frequency, their order and their Q factor. That's it.
I don't know what you mean saing "hi/lo are for peq", I mean LP/HP filters with Gain and possibility to adjust the slope of the cut on wished frequency.
High and low pass filters are currently available in manual PEQ only. You cannot use a single.WiiM Pro or Pro Plus to implement a crossover e.g. between main speakers and a subwoofer. You could use two if them grouped together for that task.
Currently, the order of the filter is not customisable, indeed. Also the visual representation of filter Q is wrong.
