We are looking for solution for 8-ch audio EQ.
Currently , we already controlled EQ by MCU , base on Calculating Filter Coefficients to Store in a Microcontroller
But , we would like to design an graphic EQ. as below.
The EQ_frequency response will Influence each other (depend on Q factory and gain value) . It look not easy to draw this curve.
Is there any formula can design transfer curve as Sigma Studio?
Thanks for your help.
