the coefficients of biquad do not match
Hello! I'm writing code for a microcontroller, and I've reached the stage of equalization, but I'm facing difficulties. In the sigma studio window, the coefficients differ from the generator built int

Write Biquad Coefficients through SPI
Hello, After uploading the schematic shown in the photo to the ADAU1467z, I exported the file and set it up to be remotely controlled via a Teensy 4.0. I used an SPI connection, and I confirmed that t

How to make really slow filters on ADAU1466
For the thermal simulation (and limiting) of one of our products we need a 0.5 mHz filter to track a thermal time constant of something getting hot over time. I've tried an IIR filter with single orde

sometimes，mcu use spi protocol write to ADAU1452 with biquad params is failed。
Hello ,everyone. I have a question，it is right when i download one biquad or several numbers biquads ，but when i download too many biquads(30-80) ，i used AP test the frequency response have different.

How to update fastDSP parameters with the sigmaDSP?
Hi, I have an EVAL-ADAU1787z and I'm trying to build an application in sigma studio where I can update the biquad parameters on the fastDSP from the sigmaDSP. From the manual I can read this: "There i

Are the lookup 2nd order filters double precision?
General 2nd order filter lets you choose between single or double precision, but the 2nd order lookup and 2nd order lookup/slew don't. Are they single or double precision? Audio Signal Processors adau
