Abstract
An apparatus for providing direction information based on a reproduced audio signal with an embedded watermark includes a signal processor, 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 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 includes a direction information provider for providing direction information based on the receiver-specific information for each received watermarked audio signal.
