A Practical Comparison of Three Tetrahedral Ambisonic Microphones

摘要

This paper compares two low-cost tetrahedral ambisonic microphones, an experimental microphone and a Core Sound TetraMic with a Soundfield MKV or SPS422B serving as a standard for comparison. Recordings were made in natural environments, of live performances, and in a recording studio. The results of analytical and direct listening tests of these recordings are discussed in this paper. A description of the experimental microphone and the recording setup is included.
