I refer the "FilterMathFilterCalculations.pdf". But there are no equations for 2 order low shelf and high shelf filter.
Is there any document about that, please?
Please refer to the below page for Low-Shelf and High-Shelf filter coefficient computation.
I have another question. If I want to design a GUI on PC and it can control the EQ in the DSP.
Should I use the EQ equation to calculate the coefficients then package it to SPI protocol. Then send it to dsp.
Or I should set all the possible 5 coefficients to arrays and build in memory.
And you know the EQ's equation parameter have Q, fc, boost, gain. And they are dependent. I think it is too many data.
If I want to use the equation to calculate the coefficients. How can I translate the data to the format 32bits like
the SigmaStudio send to sharc?
Based on your requirement and use-case, you may decide one of the below options.
