Replacement of an encoded audio output signal is disclosed. In one example, a data set comprising a first encoded audio output signal and associated pre-stored digital audio input signals captured with a microphone array of an apparatus is received. An intermediate audio signal is produced by applying an audio processing modification to the digital audio input signals. The audio processing modification utilizes apparatus specific information. The specific audio processing modification to use is determined based on user input or other information. The intermediate audio signal is encoded to produce a second encoded audio output signal. The first encoded audio output signal is replaced with the second encoded audio output signal in the data set.
