Abstract:
An apparatus for generating a sound field description having a representation of sound field components, including a direction determiner for determining one or more sound directions for each time-frequency tile of a plurality of time-frequency tiles of a plurality of microphone signals; a spatial basis function evaluator for evaluating, for each time-frequency tile of the plurality of time-frequency tiles, one or more spatial basis functions using the one or more sound directions; and a sound field component calculator for calculating, for each time-frequency tile of the plurality of time-frequency tiles, one or more sound field components corresponding to the one or more spatial basis functions evaluated using the one or more sound directions and a reference signal for a corresponding time-frequency tile, the reference signal being derived from one or more microphone signals of the plurality of microphone signals.

Claim (Index 8):
The apparatus of  claim 1 ,\n wherein the spatial basis function evaluator is configured to use for a spatial basis function, a parameterized representation, wherein a parameter of the parameterized representation is a sound direction, and to insert a parameter corresponding to the sound direction into the parameterized representation to acquire an evaluation result for each spatial basis function; or wherein the spatial basis function evaluator is configured to use a look-up table for each spatial basis function comprising, as an input, a spatial basis function identification, and the sound direction, and comprising, as an output, an evaluation result, and wherein the spatial basis function evaluator is configured to determine, for the one or more sound directions determined by the direction determiner, a corresponding sound direction of the look-up table input or to calculate a weighted or unweighted mean between two look-up table inputs neighboring the one or more sound directions determined by the direction determiner; or wherein the spatial basis function evaluator is configured to use for a spatial basis function, a parameterized representation, wherein a parameter of the parameterized representation is a sound direction, the sound direction being one-dimensional, such as an azimuth angle, in a two-dimensional situation or two-dimensional, such as an azimuth angle and an elevation angle, in a three-dimensional situation, and to insert a parameter corresponding to the sound direction into the parameterized representation to acquire an evaluation result for each spatial basis function.
