APPARATUS FOR MERGING SPATIAL AUDIO STREAMS Russian patent published in 2014 - IPC H04S3/00 

FIELD: information technology.

SUBSTANCE: method comprises estimating a first wave representation comprising a first wave direction measure characterising the direction of a first wave and a first wave field measure being related to the magnitude of the first wave for the first spatial audio stream, having a first audio representation comprising a measure for pressure or magnitude of a first audio signal and a first direction of arrival of sound; estimating a second wave representation comprising a second wave direction characterising the direction of the second wave and a second wave field measure being related to the magnitude of the second wave for the second spatial audio stream, having a second audio representation comprising a measure for pressure or magnitude of a second audio signal and a second direction of arrival of sound; processing the first wave representation and the second wave representation to obtain a merged wave representation comprising a merged wave field measure, a merged direction of arrival measure and a merged diffuseness parameter; processing the first audio representation and the second audio representation to obtain a merged audio representation, and forming a merged audio stream.

EFFECT: high quality of a merged audio stream.
