摘要： A method for rendering a spatial audio signal that represents a sound field in a selectable viewpoint audio environment that includes one or more audio objects associated with respective audio content and a respective position in the audio environment. The method includes receiving an indication of a selected listening position and orientation in the audio environment; detecting an interaction concerning a first audio object on basis of one or more predefined interaction criteria; modifying the first audio object and one or more further audio objects linked thereto; and deriving the spatial audio signal that includes at least audio content associated with the modified first audio object in a first spatial position of the sound field that corresponds to its position in the audio environment in relation to said selected listening position and orientation, and audio content associated with the modified one or more further audio objects.

摘要： A method, apparatus and computer readable medium is described in which audio data from multiple directions are received at a first user device (such as a mobile communication device). Instructions are received at the first user device from a remote device. An audio focus arrangement in the form of a direction-dependent amplification of the received audio data is generated. The audio focus arrangement is dependent on an orientation direction of the first user device and is modified in accordance with the instructions from the remote device.
