利用谱减算法实现对航空录音的处理。主要思想是相对语音进行加噪声，然后再利用算法去噪声，比较前后信噪比的变化。根据实验结构，去噪效果明显。(The use of spectral subtraction algorithm for handling aviation record. The main idea is to increase the relative voice to the noise, and then use the algorithm to noise, signal to noise ratio before and after the change. According to the experimental structure, de-noising effect is obvious.)
