Dear All,
I have to create a filter lowshelf using Q factor but camillaDSP uses just the slope up to 12.
So I tried to use the biquad free type filter, calculating it (I have considered 48kHz as simple rate reference). Unfortunately when I inserted the values the filter is completely wrong.
I cannot understand if it is an error of mine or not.
The filter is:
Lowshelf:
Filter 1: ON LSC Fc 50 Hz Gain 8 dB Q 1.0
Free:
a1: -1.994787671268450
a2: 0.994814629412255
b0:1.001526633391540
b1:-1.994767292442540
b2:0.993308374846632
Can someone help me to understand the issue?
Thank you very much.
