MATLAB scripts for ambisonic encoding of signals from EMAs and SMAs

You might recall our work on equatorial microphone arrays, EMAs, (which are composed of a spherical baffle with microphones along its equator) that we highlighted in this post and demoed in this post. Such a setup needs only 2N+1 microphones to … Continue reading
