Abstract:
According to an example embodiment, a technique for spatial audio processing on basis of two or more input audio signals that represent an audio scene and at least one further input audio signal that represents at least part of the audio scene is provided, the technique including identifying a portion of interest (POI) in the audio scene; processing the two or more input audio signals into a spatial audio signal where the POI in the audio scene is suppressed; generating, on basis of the at least one further input audio signal, a complementary audio signal that represents the POI in the audio scene; and combining the complementary audio signal with the spatial audio signal to create a reconstructed spatial audio signal.
