Apparatus and method for encoding or decoding of precomputed data for rendering early reflections in AR/VR systems

An apparatus (300) for generating one or more audio output signals from one or more encoded audio signals according to an embodiment is provided. The apparatus (300) comprises an input interface (310) for receiving the one or more encoded audio signals and for receiving additional audio information data. Furthermore, the apparatus (300) comprises a signal generator (320) for generating the one or more audio output signals depending on the encoded audio signals and depending on second additional audio information. The signal generator (320) is configured to obtain the second additional audio information using the additional audio information data and using first additional audio information, if the additional audio information data exhibits a redundancy state. Moreover, the signal generator (320) is configured to obtain the second additional audio information using the additional audio information data without using the first additional audio information, if the additional audio information data exhibits a non-redundancy state.
