METHOD AND APPARATUS OF ADAPTIVE AUDIO GAIN ADJUSTMENT IN MULTIPLE MIC BASED SOUND QUALITY ENHANCEMENT SYSTEM

摘要

The present invention relates to sound improvement and, more specifically, an adaptive audio gain control method in a multiple microphone based sound improving system and a device for the same. The present invention provides a fixed tone by adaptively reacting when the kind of noise are changed and has a low voice loss in an abnormal noise environment of a low signal to noise ratio (SNR). The present invention can process an impulse noise at real time when the kind of the noise is suddenly changed and correspond to the impulse noise at real time. The present invention also uses low power according to a small calculation rate and improves versatile properties by providing a solution for a software type library. The present invention requires tuning of a short time.
