发明名称 Regulation of volume of voice in conjunction with background sound
摘要 An audio information processing system, which when incorporated in home audio video systems, provides independent volume control capability, independent equalization setting capability and independent special effects capability of voice and background sound, to the home audio-video system. The audio information processing system receives an audio signal and extracts there from a voice signal and a background signal based upon correlation of language tracks, correlation of a center channel with surround sound channels, via a voice detection circuit, or via other means. Once the voice signal and background signal are determined, separate processing is performed, and combining of the separately processed voice and background signals may be performed.
