Abstract

An apparatus for microphone positioning includes a spatial power distribution determiner and a spatial information estimator. The spatial power distribution determiner is adapted to determine a spatial power density indicating power values for a plurality of locations of an environment based on sound source information indicating one or more power values and one or more position values of one or more sound sources located in the environment. The spatial information estimator is adapted to estimate acoustic spatial information based on the spatial power density.
