MATLAB scripts for ambisonic encoding of signals from EMAs and SMAs

Posted on 24. October 2022 by Jens Ahrens

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 →

Article: The Equatorial Microphone Array for Binaural Rendering

Posted on 4. August 2021 by Jens Ahrens

We proudly announce that the Journal of the Acoustical Society has just published our proposition of the equatorial microphone array (EMA): DOI: 10.1121/10.0005754  [ pdf ] The EMA is essentially a spherical microphone array (SMA) but with microphones only along the equator. Our … Continue reading →
