I am using evaluation board EVAL-ADAU1452MINIZ for designing a noise cancellation model using NLMS filter. The audio input used it a two-channel recorded speech from MRI environment. I used this model in various Sigma Studio versions(v3.13,v3.14,v3.15), but yet to get a nice output. Can you please let me know where I did the mistake?. attached are the design and the audio used.
