SigmaStudio General 2nd order block bypass function with Phase Shift enabled
Hi, I'm working on a speaker crossover project based on ADAU1466. Could you please confirm what is the expected behavior of Enable/Bypass button of General 2nd order filter block? I noticed that even

1st order All Pass Filter formula for phase adjustment
Hello, Since I want to use 1st order All Pass Filter to build the adjustable phase function, the old post has the other way to get 0/90/180/270 degree, but what I want is more precisely so I search th

Ultra-strange filter problem..
Hi! While evaluating the second revision of my DSP board, I noticed some super strange behaviour that is caused by a 2nd order lowpass filter. See for yourself. This is basically what you would expect

Does there has "Half-Order Filter" (3dB/oct) ?
Hello, I am trying to make a 3dB/oct High-Pass Filter, maybe it can call "half-order"? Because as I know the basic order for the first-order filter is 6dB/oct, but how can I make a 3dB/oct filter? her

How to use Auto EQ filter coefficients in general 2nd order filter?
I am happy to find the Auto EQ module in Sigma Studio to generate filter coefficients for EQing a speaker but am unsure of how to implement those filter coefficients. The Auto EQ wiki says to use a Ge

The Nth Order Filter
This filter has shown up unceremoniously in recent SigmaStudio betas, and it's immensely useful. Previously, to make a sharp filter we had to cascade a number of first and second-order sections, Their

MATLAB SOS matrix to cascaded IIR blocks for higher order filters
I have been trying to implement a filter I designed in MATLAB using the 2nd order IIR blocks in SigmaStudio but with no luck... I found that MATLAB's filter design tool will output a filter in a matri
