Definitions
- An environmental condition can be described by the impulse response of the environment.
- the object of the present invention is represented by a forward direction for controlling a wave field synthesis renderer means according to claim 1, a method for on ⁇ controlling a wave field synthesis renderer means according to claim 11 or a computer program according to claim 12 dissolved.
- FIG. 2 shows an exemplary audio object
- FIG. 4a shows a data stream which is transmitted from left to right according to FIG. 4a, that is to say from device 0 for processing FIG. 1 to one or more wave field synthesis renderers 3.
- the data stream for each audio object in FIG 4 a an embodiment has first shown a header H in which the position information and the time information are located, and a subordinate audio file for the specific au- a dio object which is designated in FIG. 4a with AO1 for the first audio object, A02 for the second audio object etc.
- a wave field synthesis renderer then receives the data stream and detects z. B. to an existing and agreed synchronization information that now comes a header. Based on another synchronization information, the renderer then recognizes that the header is now over. Alternatively, a fixed length in bits can also be agreed for each header.
