Abstract

Ein Mischpult (300) zum Verarbeiten zumindest eines ersten und eines zweiten Quellsignals und zum Bereitstellen eines abgemischten Tonsignals umfasst einen Tonsignalerzeuger (100) zum Bereitstellen eines Tonsignales (120) für eine virtuelle Abhörposition (202) innerhalb eines Raumes (200), in dem eine akustische Szene von zumindest einem ersten Mikrofon (204) an einer ersten bekannten Position innerhalb des Raumes (200) als das erstes Quellsignal (210) und von zumindest einem zweiten Mikrofon (206) an einer zweiten bekannten Position innerhalb des Raumes (200) als das zweite Quellsignal (212) aufgezeichnet wird. Der Tonsignalerzeuger (100) umfasst eine Eingangsschnittstelle (102), die ausgebildet ist, um das von dem ersten Mikrofon (204) aufgenommene erste Quellsignal (210) und das von dem zweiten Mikrofon (206) aufgenommene zweite Quellsignal (212) zu empfangen und eine Geometrieprozessor (104), der ausgebildet ist, um basierend auf der ersten Position und der virtuellen Abhörposition (202) eine erste Geometrieinformation (110) und um basierend auf der zweiten Position und der virtuellen Abhörposition (202) eine zweite Geometrieinformation (112) zu bestimmen. Ein Signalerzeuger (106) zum Bereitstellen des Tonsignales (120) ist ausgebildet, zumindest das erste Quellsignal (210) und das zweite Quellsignal (212) gemäß einer die erste Geometrieinformation (110) und die zweite Geometrieinformation (112) verwendenden Kombinationsregel zu kombinieren.
