| 摘 要： | 噪声消除用于有效地去除音频数据中的噪声，而对音质的影响很小。为了进行此项处理，必须先确定一个要去除的噪声的样品。该功能最适于处理连续出现的背景噪声，如空调声、嗡嗡声、磁带的咝咝声。

| Abstract: | The noise reduction function can be used to effectively remove annoying noise material from the audio with very little or almost no discoloration of the original audio. For this function the algorithm needs an example of the noise print that needs to be removed. This function works best with types of noises such as a constant occurrence of a ground loop, air conditioner, hum, tape hiss or feedback. |
