摘要：
An apparatus (100) for merging a first spatial audio stream with a second spatial audio stream to obtain a merged audio stream comprising an estimator (120) for estimating a first wave representation comprising a first wave direction measure and a first wave field measure for the first spatial audio stream, the first spatial audio stream having a first audio representation and a first direction of arrival. The estimator (120) being adapted for estimating a second wave representation comprising a second wave direction measure and a second wave field measure for the second spatial audio stream, the second spatial audio stream having a second audio representation and a second direction of arrival. The apparatus (100) further comprising a processor (130) for processing the first wave representation and the second wave representation to obtain a merged wave representation comprising a merged wave field measure and a merged direction of arrival measure, and for processing the first audio representation and the second audio representation to obtain a merged audio representation, and for providing the merged audio stream comprising the merged audio representation and the merged direction of arrival measure.
