Peaking filter coefficients calc
Thread Summary
The user sought correct formulas for calculating coefficients for peaking filters in parametric EQs for the ADAU1451 DSP. The final answer directed the user to post a new question if further assistance is needed, while an accompanying answer suggested using a working calc file from the 'Calculating Filter Coefficients to Store in a Microcontroller' document, noting that some coefficients need to be inverted for accurate results.AI Generated Content
Good day!
Where I can find correct formulas for calculating coefficients for peaking filters, using in parametric EQs for ADAU1451 DSP.
I found that page General Filters [Analog Devices Wiki] , but only parametric there is. I try to use this formula (I use EXEL and Sigma Studio for compare), and the results are near at positive value of dBBoost, and different at negative value of dBBoost. I attach my test Exel File)
Search give nothing, or I`m bad googler)))
I found only that Peaking filter transfer function But there is no answer((
It will be perfect, if somewhere is formulas for all types of filters in parametric EQs. And good too, if there is formulas for creating the same plots like in Sigma Studio.
Finaly, I`m going to do external interface for changing audio processing parametrs with using microcontroller or ARM microprocessor in Web Panel interface.
Thanks!

I have found working calc file there Calculating Filter Coefficients to Store in a Microcontroller
But it have one moments - some coeff need to be inverted.
