近十年来，噪声门（NOISEGATE）已成为处理音频信号的基本装置之一。噪声门的设计随着使用经验的积累而得到不断的改进。多通道和多功能的噪声门层出不穷，甚至让人目不暇接。其实，任何一种所谓具有独特创造性的噪声门，就其原理及应用方面都是万变不离其宗的。了解和掌握了一 For nearly a decade, NOISEGATE has become one of the basic devices for handling audio signals. Noise gate design with the use of accumulated experience and get continuous improvement. Multi-channel and multi-function noise gate after another, or even dizzying. In fact, any kind of so-called unique and creative noise gate, its principle and application are the same. Understand and master one
