关于掩蔽效应阈值函数

ｗａｖｅ：小波包分解，对信号进行小波包分解，将信号按频率成分分解出来，并且估计小波包能量-wave: wavelet packet decomposition, wavelet packet decomposition of the signal, the signal decomposition by frequency components out, and the estimated wavelet packet energy

语音噪声压缩新算法,一种基于vad的语音噪声抑制方法。这种新算法源于vad 技术及谱减法，它先对含噪声信号进 行vad处理，而后是基于感知掩蔽阈值的谱减法运算，降低噪声，获得清晰的增强信号。与其它算法相比，其效果更好，语 音听测试证明了这一点。-New algorithm for speech compression noise, a noise reduction of speech based vad method. Thi
