AB  - As a spatial-sound processing technique, directional audio coding can determine the direction of arrival of a sound wave. When based on a square array of four omnidirectional microphones, reliable estimation of direction is limited to a restricted frequency range. However, when a rigid cylinder is inserted into the array, the resulting acoustic shadows and scattering allow intermicrophone differences to be used in the quantization. Both methods estimate the direction reliably over the entire audible frequency range. Subjective listening tests corroborate the objective computations.
