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
Database of Sound Source Directivities
We have collected a considerable amount of measurement data on sound source directivities: https://github.com/AppliedAcousticsChalmers/sound-source-directivities The sources are mostly loudspeakers, the human voice, and musical instruments that are used in classical orchestras. Here’s an example set of balloon plots of the directivity of … Continue reading
