用於音效處理的matlab code，內有多項examples及演算法！(algorithms for audio processing)

BALLBEAM demonsrates Proportional-Derivative (PD) control as applied to a ball and beam simulation experiment. Execute by calling with no arguments. P and PD controllers are implemented which manipulates the beam angle in response to the position of the ball on the beam. The setpoint is indicated by the red marker and adjusted using the slider at the bottom of the figure. The control gain, Kc, and the Derivative Time constant, Td, are adjusted by a sliders located in the right hand control panel. Simulation data is stored in ballbeam.mat for subsequent analysis and parameter estimation. This demo was originally developed with Matlab 5.3 and Matlab 6.0. Some of the user interface code was shamelessly ripped out of the standard Matlab demos. The demo is now updated for Matlab 2010b with additional documentation and suggested exercises for classroom use.

说明：  计算mfcc的函数，mfcc在音频分类中相当重要(Mfcc function calculation, mfcc very important in the audio category)

光学弗朗和费衍射模拟的Matlab源代码(Fraunhofer diffraction optical analog of the Matlab source code)

卡尔曼滤波中，前后平移的函数。这是最基本的算法(Before and after kalman filter, the translation function.This is the most basic algorithm)

this is a good matlab code for image enhancement technique

在SNR=10db，干扰为高斯噪声的条件下进行信号调制类型的自动识别。(SNR = 10db, interfere with the automatic identification of the type of signal modulation under Gaussian noise conditions. )

matlab开发，在Vs2010里配置matlab调用环境(matlab developer)

在齿轮箱故障诊断中，需要对故障信号进行特征提取，本程序是齿轮箱特征提取源代码。(Gearbox fault diagnosis, the need for fault signal feature extraction, the procedure is to extract the source code gearbox features.)
