    Abstract: According to an example embodiment, a method for processing an input audio signal in accordance with spatial metadata so as to play back a spatial audio signal in a device in dependence of at least one sound reproduction characteristic of the device is provided, the method comprising: obtaining said input audio signal and said spatial metadata; obtaining said at least one sound reproduction characteristic of the device; rendering a first portion of the spatial audio signal using a first type playback procedure applied on the input audio signal in dependence of the spatial metadata, wherein the first portion comprises sound directions within a front region of the spatial audio signal; and rendering a second portion of the spatial audio signal using a second type playback procedure applied on the input audio signal in dependence of the spatial metadata and in dependence of said at least one sound reproduction characteristic, wherein the second portion comprises sound directions that are not included in the first portion and where the second type playback procedure is different from the first playback procedure and involves cross-talk cancellation processing.
