Hi Sir,

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.
