实现模拟的房间混响功能，是国外著名的学者编写的image-method的仿真程序，经计算有用-Analog room reverberation function, is famous scholars prepared image-method simulation program, calculated helpful

schroeder方法混响仿真，模拟混响环境获得接收音频-Schroeder method of reverberation simulation, simulated reverberation environment for receiving audio

针对室内麦克风阵列仿真信号的产生，有混响，可以添加任意角度的噪声。(For indoor microphone array simulation signal generation, reverberation, can add any angle noise.)
