I am using the latest Sigma Studio. I did a search and found you have a wind noise filter. But I am using the ADAU1452 DSP. What filters can I use from the software to reduce background noise? Or do you have any SDK kits that may work with Sigma Studio? I was going to use my audio card and record the noise and perform a frequency response. My mike is a stereo condenser type. Possible using the black sound absorption material will help?
