Abstract:

In one embodiment the present invention includes a circuit for automatically adjusting an output of an audio device. The circuit includes a memory circuit, a detector circuit, a control circuit, and an output circuit. The memory circuit stores configuration information. The detector circuit detects environment information related to an environment in which the apparatus is present. The control circuit selects selected configuration information from the memory circuit according to the environment information detected by the detector circuit. The output circuit receives an input audio signal and the selected configuration information, modifies the input audio signal according to the selected configuration information, and generates an output audio signal corresponding to the input audio signal as modified according to the selected configuration information.
