Therefore, a single run of the noise gate is often not enough to get rid of all the noise. Higher-amplitude short clicks among the noise can open the noise gate and let the noise through. Therefore, a single loud click, even a very short one, can open the gate. Once the amplitude exceeds the threshold, the gate opens. Not enough reductionДЄ typical noise gate (including noisegate.ny) closes when the loudness (or, more precisely, the amplitude) of the signal falls below a specified threshold. But before I get into that, let me explain in more detail the ways in which the usual noise gate plugins fall short. So I implemented my own noise gate plugin that addresses these issues-and it is also much faster.

There are two major drawbacks of that plugin, which I can summarize as: The de-facto standard noise gate plugin for audacity, noisegate.ny, does a pretty good job emulating an analog noise gate but also doesnвЂ™t do much beyond that. To soften the transition, the gate doesnвЂ™t open/close immediately but goes through the attack and decay phases, spread across a short amount of time, like 50ms. When the gate is closed, the output is suppressed to remove the noise when the gate is open, the input goes to the output unchanged. It would notice when audio went either above or below the threshold, and вЂњopenвЂќ or вЂњcloseвЂќ the gate correspondingly. It doesnвЂ™t remove the noise from under the speech-thatвЂ™s called noise reduction-but it removes the noise between the phrases.Д«ack when audio processing was analog and real-time, the noise gate had to be simple. It detects the parts of the audio signal with very low volume, where nothing is happening apart from the background noise, and either reduces the volume further or silences it completely.
