suppression of acoustic noise in speech using spectral subtraction

Power Spectral Subtraction (SS) for speech enhancement Storing original signal to compute PESQ & SSNR measurment Noise magnitude calculations - assuming that the first 5 frames is noise/silence

谱减法的噪声消除Spectral subtraction noise elimination-Spectral subtraction noise elimination

New algorithm for speech compression noise, a noise reduction of speech based vad method. This new algorithm derived vad technology and spectral subtraction, it firstly deal with the noise signal vad, then the masking threshold is based on perception
