ADPCM_code
- DPCM是differential pulse code modulation的缩写，也就是差分脉冲编码调制的意思。他的主要思想是通过已知的数据预测下一个数据，然后传递预测值与实际值之间的差值。-DPCM is a differential pulse code modulation acronym, that is, differential pulse code modulation mean. His main idea is known to the data through a dat
pitch_
- 求pcm文件的基音周期，用matlab编写，作图说明，用平均幅度差算法修正自相关算法来求基音周期-Find the pitch period pcm files, using matlab, plot descr iption, with the average magnitude difference algorithm for auto-correlation algorithm to find correct pitch
PESQ
- PESQ语音质量测试工程.主要用于测试修改或者经过编码压缩或者信息隐藏的音频文件和原始音频文件在声音质量上的区别.得到的值越大表示两个文件差异越小-PESQ voice quality testing project is mainly used to test modifications or through coding or information hiding audio files and raw audio files on the sound quality difference
JIDAJIXIAO
- 极大极小化准则和贝叶斯准则有些相似，唯一不同点就是极大极小准则无法确定先验。利用matlab编写极大极小化准则。-Minimax and Bayesian criteria of the guidelines are somewhat similar, the only difference is the minimax criterion can not be determined a priori. Use matlab write great minimization criteria.
Log_Spectral_Distance
- 使用LSD，即对数倒谱距离（Log_Spectral_Distance）来评判重构出来信号与原始信号之间的差异。(It uses the Log_Spectral_Distance to judge the difference between the original signal and the restructed signal.)
order
- matlab实现的阶次分析算法，用于变转速机械故障特征提取，可运行，包含寻找脉冲时刻，等角度时刻，数字跟踪滤波，样条差值等步骤(The order analysis algorithm realized by Matlab is used to extract the fault features of variable speed machinery. It can be operated, including the steps of finding impulse moment, equa
