Performance difference between Slew filter and Parametric EQ
Dear Team, Thank you for your support. My overall expectation is to have smooth filtering while switching from one gain level the other, hence I have chosen Slew filter instead of Parametric EQ. But,

Problem with ADAU1452 and SigmaStudio 4.7, audio amplitude oscillates uncontrolled
Hello, We've been using for a long time Sigma Studio with a ADAU1401A for an old project. We upgraded to the ADAU1452 for having delay functions, and we re-made the program to be the same. We've encou
