A DYNAMIC AUDIO CONTROL CIRCUIT AND METHOD

摘要

A dynamic audio control circuit (10) and method receives audio type information (70) or audio information (670) embedded in an audio signal (72, 672) and in response dynamically adjusts the audio signal (72, 672) without user intervention. The dynamic audio control circuit (10) may adjust equalization and time delay parameters based on, for example, an audio spectrum analysis of the received audio information (670) embedded in the audio signal (672). According to one embodiment, the audio type information (70) may be, for example, descriptive information such as station and program information transmitted along with a standard radio, television or satellite broadcast. According to another embodiment, the audio type information (70) may be equalization and time delay settings associated with the audio signal (72). The audio characterization information (74, 674) may be used to characterize the audio signal (72, 672) in order to provide a basis for adjusting or customizing the audio signal (72, 672) to the taste of the user.
