Method for recording and playing back sound sources with time-varying directional characteristics

摘要

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 tau in relation to the first reproduction unit.
