Using Ambisonics to Reconstruct Measured Soundfields
Spherical microphone arrays can measure a soundfield's spherical harmonic components, subject to certain bandwidth constraints depending on the array radius and the number and placement of the array's sensors. Ambisonics is designed to reconstruct the spherical harmonic components of a soundfield via a loudspeaker array and also faces certain limitations on its accuracy. This paper looks at how to reconcile these sometimes conflicting limitations to produce the optimum solution for decoding. In addition, binaural modeling is used as a method of evaluating the proposed decoding method and the accuracy with which it can reproduce a measured soundfield.
