Abstract
Mechanisms for obtaining an audio signal and information relating to the recording conditions of the audio signal are provided, the method comprising: obtaining an audio signal, wherein the audio signal is a voltage signal representation of sound, the voltage signal having been converted from a pressure signal; obtaining first information indicative of at least one objective feature and/or at least one perceptual feature associated with the conversion of the pressure signal into the audio signal in the form of a voltage signal representation; storing the audio signal, the first information, and second information identifying a relationship between the audio signal and the first information; determining an error adjustment for adjusting the audio signal based on the obtained information; applying the error adjustment to the audio signal to create an error-adjusted audio signal; and obtaining an audio signal and information relating to the recording conditions of the audio signal.
