A method of adjusting the amplitude of an audio signal (302) is described. The method comprises a user (230) selecting or pre-determining user selected minimum (318) and maximum (314) output audio signal amplitudes, through, for example, either preset profile selection or an in-situ calibration process; and a processor processing or transforming the input audio signal (302) into an output audio signal such that the output audio signal amplitude is within minimum (318) and maximum (314) output audio signal amplitudes derived from the user selected minimum and maximum output audio signal amplitudes. The processing occurs unless the output audio signal conflicts with another pre-determined criterion like, for instance, dynamic range preservation. A corresponding device (100) is also described. |
