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 14):
The apparatus of  claim 9 , wherein the direct or diffuse sound determiner is configured to:\n calculate the direct portion and the diffuse portion from a single microphone signal, and wherein the diffuse sound component calculator is configured to calculate the one or more diffuse sound components using the diffuse portion as the reference signal, and wherein the sound field component calculator is configured to calculate the one or more direct sound field components using the direct portion as the reference signal; or calculate a diffuse portion from a microphone signal being different from the microphone signal, from which the direct portion is calculated, and wherein the diffuse sound component calculator is configured to calculate the one or more diffuse sound components using the diffuse portion as the reference signal, and wherein the sound field component calculator is configured to calculate the one or more direct sound field components using the direct portion as the reference signal; or calculate a diffuse portion for a different spatial basis function using a different microphone signal, and wherein the diffuse sound component calculator is configured for using a first diffuse portion as the reference signal for an average spatial basis function response corresponding to a first number, and to use a different second diffuse portion as the reference signal corresponding to a second number average spatial basis function response, wherein the first number is different from the second number, and wherein the first number and the second number indicate any order or level and mode of the one or more spatial basis functions; or calculate the direct portion using a first multichannel filter applied to the plurality of microphone signals and calculating the diffuse portion using a second multichannel filter applied to the plurality of microphone signals, the second multichannel filter being different from the first multichannel filter, and wherein the diffuse sound component calculator is configured to calculate the one or more diffuse sound components using the diffuse portion as the reference signal, and wherein the sound field component calculator is configured to calculate the one or more direct sound field components using the direct portion as the reference signal; or calculate the diffuse portions for different spatial basis functions using different multichannel filters for the different spatial basis functions, and wherein the diffuse sound component calculator is configured to calculate the one or more diffuse sound components using the diffuse portion as the reference signal, and wherein the sound field component calculator is configured to calculate the one or more direct sound field components using the direct portion as the reference signal.
