[THIERGART OLIVER, KUECH FABIAN, SCHULTZ-AMLING RICHARD, KALLINGER MARKUS, DEL GALDO GIOVANNI, KUNTZ ACHIM, MAHNE DIRK, PULKKI VILLE, LAITINEN MIKKO-VILLE] A spatial audio processor for providing spatial parameters based on an acoustic input signal comprises a signal characteristics determiner and a controllable parameter estimator. The signal characteristics determiner is configured to determine a signal characteristic of the acoustic input signal. The controllable parameter estimator for calculating the spatial parameters for the acoustic input signal in accordance with a variable spatial parameter calculation rule is configured to modify the variable spatial parameter calculation rule in accordance with the determined signal characteristic.
