Abstract
Techniques pertaining to providing an appropriate recording mode to achieve optimum record data in accordance with the recording environment are described. In one embodiment, a current audio recording mode is initially selected to be one of a low sensitivity audio recording mode and a high sensitivity audio recording mode. A digital gain for digital audio recording data in the current audio recording mode is obtained. The current audio recording mode is automatically switched between the low sensitivity audio recording mode and the high sensitivity audio recording mode when the digital gain reaches a gain threshold.
