Claim Text:
1. An apparatus for providing an output signal to an audio transducer, comprising: an analog signal path portion having an audio input for receiving an analog input signal, an audio output for providing the output signal, and a selectable analog attenuation, and configured to generate the output signal based on the analog input signal and in conformity with the selectable analog attenuation; a digital-to-analog converter (DAC) having a selectable digital gain and configured to convert a digital audio input signal into the analog input signal in conformity with the selectable digital gain; and a control circuit configured to select the selectable analog attenuation and select the selectable digital gain based on a magnitude of a signal indicative of the output signal; wherein at least one of the analog signal path and the DAC is further configured to modify a response of the analog audio signal to reduce filtering effects occurring as a result of a change in the selectable digital gain.
