An apparatus for audio processing including a first device (e.g., a multiplier, digital signal gain module, etc.) adapted to apply a gain to a first digital audio signal to generate a second digital audio signal; a second device (e.g., a digital-to-analog converter (DAC), etc.) adapted to generate an analog audio signal from the second digital audio signal; a third device (e.g., a detector, sensor, user interface, etc.) adapted to generate an audio characteristic signal related to a characteristic of the first or second digital audio signal, or the analog audio signal; and a fourth device (e.g., a controller, control module, etc.) adapted to control the gain of the first device based on a first function of the audio characteristic signal, and control a power supplied to the second device based on a second function of the audio characteristic signal. |
