Abstract: According to an example embodiment, a method for processing two or more microphone signals is provided. The method includes deriving a first captured audio signal having one or more channels based on the two or more microphone signals received from respective two or more microphones in accordance with capture control data that identifies at least one characteristic for derivation of the first captured audio signal; storing at least part of the capture control data and intermediate audio data derived based on the two or more received microphone signals; deriving modified capture control data as a combination of the stored capture control data and user-definable post-capture control data that identifies at least one characteristic for derivation of a second captured audio signal; and deriving the second captured audio signal having one or more channels based on said intermediate audio data in accordance with the modified capture control data.
