Abstract
A method includes performing, at a processor, signal processing operations on signals captured by each microphone in a microphone array. The method also includes performing a first directivity adjustment by applying a first set of multiplicative factors to the signals to generate a first set of ambisonic signals. The first set of multiplicative factors is determined based on a position of each microphone in the microphone array, an orientation of each microphone in the microphone array, or both.
