WIND NOISE SUPPRESSING SYSTEM FOR ENHANCING PERCEPTUAL QUALITY OF PROCESSED VOICE

摘要

PURPOSE: A wind noise suppressing system for enhancing perceptual quality of processed voice is provided to suppress the wind noise by learning, encoding, and then dampening the noise associated with movement of air from an input signal. CONSTITUTION: A time frequency transform process is performed to acquire transformed data for signals(206). A spectrum regulated by wind noise is identified by performing a signal analysis process for the transformed data(214). An attenuation process is performed to attenuate the wind noise of the transformed data(216). A time series is composed from the transformed data(220).
