Abstract
A method is provided for producing a volume gain applied by an amplifier to at least one audio signal according to a desired volume gain selected by a user, which includes calculating a standardized total slow sound level from at least one audio signal, calculating maximum slow volume gain and minimum slow volume gain as the quotient of the product of the desired volume gain by maximum slow gain, respectively by minimum slow gain, divided by the standardized total slow sound level, determining a first minimum out of the desired volume gain and the maximum slow volume gain, determining a second minimum out of the desired volume gain multiplied by a maximum volume gain and the minimum slow volume gain, determining as a slow volume gain the maximum of the first and second previously determined minima, and calculating the volume gain according to the slow volume gain.
