中文说明：应用程序测试有源噪声控制一个32抽头自适应FIR滤波器是用来产生一个抗噪声抵消主噪声。这里使用的自适应算法是滤波x-LMS（FXLMS）和归一化FXLMS算法
English Description：
Application Program to Test Active Noise Control a 32-tap adaptive FIR filter is used to produce an anti-noise to cancel the primary noise. The adaptive algorithms used here are the filtered-x LMS (FXLMS) and normalized FXLMS algorithms
