    摘要: An apparatus for generating a merged audio data stream is provided. The apparatus comprises a demultiplexer (180) for obtaining a plurality of single-layer audio data streams, wherein the demultiplexer (180) is adapted to receive one or more input audio data streams, wherein each input audio data stream comprises one or more layers, wherein the demultiplexer (180) is adapted to demultiplex each one of the input audio data streams having one or more layers into two or more demultiplexed audio data streams having exactly one layer, such that the two or more demultiplexed audio data streams together comprise the one or more layers of the input audio data stream. Furthermore, the apparatus comprises a merging module (190) for generating the merged audio data stream, having one or more layers, 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 comprises a pressure value of a pressure signal, a position value and a diffuseness value as audio data.

    摘要: An apparatus (100) for providing direction information based on a reproduced audio signal with an embedded watermark is provided. The apparatus (100) comprises a signal processor (110), which is adapted to process at least two received watermarked audio signals recorded by at least two audio receivers at different spatial positions. The signal processor (110) is adapted to process the received watermarked audio signals to obtain a receiver-specific information for each received watermarked audio signal. The receiver-specific information depends on the embedded watermarks embedded in the received watermarked audio signals. Moreover, the apparatus comprises a direction information provider (120) for providing direction information based on the receiver-specific information for each received watermarked audio signal.
