A wireless communication device ( 100 ) may include a receiver ( 110 ), a memory ( 104 ), a digital-to-analog converter ( 128 ), an audio playback system ( 124 ) and other features. A dynamic range controller ( 130 ) selectively generates control signals to adjust, at least in part, the operational dynamic range of the digital-to-analog converter ( 128 ) for digital signals received by the receiver ( 110 ) or stored in the memory ( 104 ). The selection of dynamic range is based on identifying a characteristic. In one embodiment, the control signals are used to selectively operate the digital-to-analog converter ( 128 ) at a particular dynamic range based on a sampling rate of a received digital audio signal.
