Phase graph

[giocapy]

My suggestion is to add the phase in all equalisation and calibration graphs. In details, it would be interesting to se the effects of the PEQ filters on the phase

WiiM EQ uses IIR filters, so the phase response is 100% determined by the amplitude response. There's also no way to change this dependency. What would you do with the additional information (and the added visual clutter)?

Admittedly, the combined phase response of multiple filters is certainly not all that easy to imagine. But again, I don't see what to make out of this extra information.

And it would not matter very much given what the loudspeakers add to the total system phase behaviour.
(I don't think adding a phase correcting FIR filter to each EQ setting should be of high priority for WiiM.)
