摘要： An apparatus for microphone positioning includes a spatial power distribution determiner and a spatial information estimator. The spatial power distribution determiner is adapted to determine a spatial power density indicating power values for a plurality of locations of an environment based on sound source information indicating one or more power values and one or more position values of one or more sound sources located in the environment. The spatial information estimator is adapted to estimate acoustic spatial information based on the spatial power density.

摘要： An apparatus for generating a merged audio data stream is provided. The apparatus includes a demultiplexer for obtaining a plurality of single-layer audio data streams, wherein each input audio data stream includes one or more layers, wherein the demultiplexer is adapted to demultiplex each one of one or more input audio data streams having one or more layers into two or more demultiplexed audio data streams having exactly one layer. Furthermore, the apparatus includes a merging module for generating the merged audio data stream based on the plurality of single-layer audio data streams. Each layer of the input data audio streams, of the demultiplexed audio data streams, of the single-layer data streams and of the merged audio data stream includes a pressure value of a pressure signal, a position value and a diffuseness value as audio data.
