Abstract
The invention relates to a method for recording sound signals of one or more sound sources located in a recording space and having time-variable directional characteristics and for reproducing the sound signals and directional information of the sound sources true to life in an area of reproduction. The invention also relates to a system for carrying out the method. In order to be able to record, transmit and reproduce the directional information of a sound source in real time, only the main direction of emission of the sound signal emitted by the sound source is detected in the recording space in a time-dependent manner and reproduction is carried out depending on the detected main direction of emission. In order to convey the directional information, the sound signals are reproduced by means of a first reproduction unit associated with the sound source and at least one second reproduction unit spaced apart from the first reproduction unit. Reproduction by means of the one or more second reproduction units proceeds with a time delay τ in relation to the first reproduction unit.

17. A method for recording sound signals of a sound source with time variable directional characteristics arranged in a recording space with sound recording means and for reproducing the sound signals in an area of reproduction using sound reproduction means, comprising:
detecting a main direction of emission of the sound signals emitted by the sound source in a time variable manner and a reproduction taking place in a manner dependent on the detected main direction of emission, wherein the reproduction of the sound signals takes place using a first reproduction unit associated with the sound source and at least one second reproduction unit spaced apart from the first reproduction unit, and the reproduction takes place with the second reproduction unit or units with time delays τ
relative to the first reproduction unit.- View Dependent Claims (18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 33, 34)
- 28. A system for recording sound signals from one or more sound sources with time variable directional characteristics with sound recording means in a recording space and for reproducing the sound signals with sound reproduction means in an area of reproduction, the system comprising a means for detecting, in a time dependent manner, the main directions of emission of the sound signals emitted by the sound source(s) and means for reproducing the transmitted sound signals in dependence on the detected directions.
