Abstract:
1. A method for reconstructing an audio signal to obtain a reconstructed audio signal, the method comprising: receiving the audio signal, the audio signal comprising at least one audio channel and a first associated direction parameter indicating a first direction of origin of a first portion in a first frequency band of a frame of the at least one audio channel with respect to a recording position and a second associated direction parameter indicating a second direction of origin of a second portion in a second frequency band of the frame of the at least one audio channel with respect to the recording position, wherein the first associated direction parameter is different from the second associated direction parameter, wherein the first direction of origin is different from the second direction of origin, and wherein the first frequency band is different from the second frequency band; selecting, by a selector, a set direction of origin with respect to the recording position to obtain a selected set direction of origin; and modifying, by a modifier, the first portion in the first frequency band of the frame of the at least one audio channel and the second portion in the second frequency band of the frame of the at least one audio channel for deriving a reconstructed portion in the first frequency band and the second frequency band of the reconstructed audio signal for the frame of the at least one audio channel, wherein the modifying comprises increasing an intensity of the first portion in the first frequency band of the frame of the at least one audio channel, when the first direction parameter associated with the first frequency band of the first portion of the at least one audio channel indicates the first direction of origin close to the selected set direction of origin with respect to the second frequency band of the second portion of the frame of the at least one audio channel for which the second associated direction parameter indicates the second direction of origin further away from the selected set direction of origin, wherein at least one of the selector and the modifier comprises a hardware implementation.
