- 本资料涵盖了几乎所有的语音增强方面的方法,主要有谱减法,听觉掩蔽,最小均方误差,维纳滤波以及一些非主流的方法,这些对于研究语音增强的人来说是很有帮助的-The data cover almost all aspects of speech enhancement methods, the main spectral subtraction, auditory masking, minimum mean square error, Wiener filtering as well as some
PCM
- 利用Matlab仿真脉冲编码调制(PCM)及A律、μ律PCM对声音进行压缩编解码过程。 脉冲编码调制(PCM,Pulse Code Modulation)是一种将模拟语音信号转换成数字信号的编码方式。波形编码器的作用是对采样后的信号样本进行量化和编码。从数学上来看,量化过程就是把一个连续幅度值的无限数集合映射成一个离散幅度值的有限数集合,编码就是用一组二进制数来表示这些映射后的有限数。国际标准化的PCM采用折叠二进制码,符合长途电话质量。根据量化方法的不同,PCM可分为均匀量化PCM和对数
