Tonsignalerzeuger, Verfahren und Computerprogramm zum Bereitstellen eines Tonsignals

The invention relates to a mixing desk (300) for processing at least one first and one second source signal and for providing a mixed sound signal comprising a sound signal generator (100) for providing a sound signal (120) for a virtual listening position (202) within a room (200), in which an acoustic scene of at least one first microphone (204) at a first known position within the room (200) is recorded as the first source signal (210) and an acoustic scene of at least one second microphone (206) at a second known position within the room (200) is recorded as the second source signal (212).; The sound signal generator (100) comprises an input interface (102) which is designed in order to receive the first source signal (210) recorded by the first microphone (204) and the second source signal (212) recorded by the second microphone (206), and further comprises a geometry processor (104) which is designed in order to determine a first item of geometry information (110) based on the first position and the virtual listening position (202) and to determine a second item of geometry information (112) based on the second position and the virtual listening position (202). A signal generator (106) for providing the sound signal (120) is designed to combine at least the first source signal (210) and the second source signal (212) according to a combination rule using the first item of geometry information (110) and the second item of geometry information (112)
