说明：  二阶巴特沃斯(Butterworth)低通滤波器(Low pass filter)

This file gives an example how to use the function "ParInfoGain.m" The user can define if a matlabpool should be used or not. This file shows an example using the well known fisher iris datafile

粒子群算法的局部模型程序，比全局模型的效果要好，尽管收敛速度慢些，但是都能找到最优点。(PSO partial model program than the overall model is better effect, despite the convergence speed more slowly, But can find the most advantages.)

Find the energy of the wave

Only coding parameters of sound generation model • LPC is an example where parameters are a1, a2, …ak , e(n) • Music instrument parameters: pitch, loudness, timbre, …Frequency Masking: If a tone of a certain frequency and amplitude is present, then other tones or noise of similar frequency cannot be heard by the human ear • the louder tone (masker) makes the softer tone The Masking Threshold is used by the audio encoder to determine the maximum allowable quantization noise at each frequency to minimize noise perceptibility: remove parts of signal that we cannot perceive
