基于matlab实现语音信号的采集和处理，包括频谱分析，显示实时A声级(Based on matlab realize the voice signal acquisition and processing, including spectral analysis, display real-time A sound level)

说明：  通常，非线性整数规划是一个具有指数复杂度的NP问题，如果约束较为复杂，Matlab优化工具箱和一些优化软件比如lingo等，常常无法应用，即使能应用也不能给出一个较为令人满意的解。这时就需要针对问题设计专门的优化算法。下面举一个遗传算法应用于非线性整数规划的编程实例，供大家参考！(Generally, nonlinear integer programming is a NP problem with exponential complexity. If the constraints are more complex, MATLAB optimization toolbox and some optimization software such as lingo are often unable to be applied, even if they can be applied, they cannot give a satisfactory solution. At this time, we need to design a special optimization algorithm for the problem. Here is an example of genetic algorithm applied to nonlinear integer programming, for your reference!)
