Abstract:
1. An apparatus adapted to determine a combined converted spatial audio signal, the combined converted spatial audio signal comprising at least a first combined component and a second combined component, from a first and a second input spatial audio signal, the first input spatial audio signal comprising a first input audio representation and a first direction of arrival, the second spatial input signal comprising a second input audio representation and a second direction of arrival, comprising: a first processor adapted to determine a first converted signal, the first converted signal comprising a first omnidirectional component and at least one first directional component, from the first input spatial audio signal, the first processor comprising wherein the first processor is adapted to provide the first converted signal comprising the first omnidirectional component and the at least one first directional component; a second processor adapted to provide a second converted signal based on the second input spatial audio signal, comprising a second omnidirectional component and at least one second directional component, the second processor comprising wherein the second processor is adapted to provide the second converted signal comprising the second omnidirectional component and at least one second directional component; an audio effect generator adapted to render the first omnidirectional component to acquire a first rendered component or to render the first directional component to acquire the first rendered component; a first combiner adapted to combine the first rendered component, the first omnidirectional component and the second omnidirectional component, or to combine the first rendered component, the first directional component, and the second directional component to acquire the first combined component; and a second combiner adapted to combine the first directional component and the second directional component, or to combine the first omnidirectional component and the second omnidirectional component to acquire the second combined component.
