Claim:
1. A spatial audio processor for providing spatial parameters based on an acoustic input signal, the spatial audio processor comprising: a signal characteristics determiner configured to determine a signal characteristic of the acoustic input signal, wherein the acoustic input signal comprises at least one directional component; and a controllable parameter estimator for calculating the spatial parameters for the acoustic input signal in accordance with a variable spatial parameter calculation rule; wherein the controllable parameter estimator is configured to modify the variable spatial parameter calculation rule in accordance with the determined signal characteristic; wherein the signal characteristics determiner is configured to determine a stationarity interval of the acoustic input signal; and wherein the controllable parameter estimator is configured to modify the variable spatial parameter calculation rule in accordance with the determined stationarity interval, so that an averaging period for calculating the spatial parameters is comparatively longer for a comparatively longer stationarity interval and is comparatively shorter for a comparatively shorter stationarity interval.
