ADAU1442 Feedback Suppression
Hello, I am new to posting here and also new to audio electronics; so my apologies in advance if my question is naive. I am designing a audio mixer amplifier and I would like to use the ADAU1442 or AD

Remove audio feedback with ad1940(dsp)
Hi everyone It is currently designed with 4 microphone inputs and 2 line outputs. DSP CHIP AD1940 (4 mic inputs) + (1 line output feedback input) = 5 total. I'm testing with SIGMASTUDIO and it's not w

ADAU1761 - Feedback module causes problem in Microcontroller integration
Hi, I have a problem with the Feedback module. I get some weird behavior of my algorithm only when I integrate it in my microcontroller. When I test it in SigmaStudio everything is fine. I have 3 Feed

How to determine which frequency band has highest magnitude
Hi all. I'm using ADAU1701 and SigmaStudio 3.10 beta. I want to design a Index Selectable Filter to cut off the audio feedback from different sources, eg: microphone, hoots and howls, Different source

illegal feedback error from double-pole MUX
Hello all, The circuit below uses a stereo, three-input mux as a DP3T switch where the "left" section chooses between two DC sources for the filter's Q input, and the "right" section selects filter or

Cheap square root via "op-amp"
SigmaStudio's square root block provides an immediate sample-to-sample output. Because it must come up with a result for every sample, however, it uses many instructions. If your application needs a s
