Gates typically feature "attack", "release", and "hold" settings and may feature a "look-ahead" function. The noise becomes most noticeable during periods where the main signal is not present, such as a bar of rest in a guitar solo. Even though the signal and the unwanted noise are both present in open gate status, the noise is not as noticeable. A noise gate does not remove noise from the signal itself when the gate is open, both the signal and the noise will pass through. The threshold is set above the level of the "noise", and so when there is no main "signal", the gate is closed.Ī common application is with electric guitar to remove hum and hiss noise caused by distortion effects units. A noise gate is used when the level of the "signal" is above the level of the unwanted " noise".

If the signal falls below the threshold, no signal is allowed to pass (or the signal is substantially attenuated): the gate is "closed". In its simplest form, a noise gate allows a main signal to pass through only when it is above a set threshold: the gate is "open". However, noise gates attenuate signals by a fixed amount, known as the range. Comparable to a compressor, which attenuates signals above a threshold, such as loud attacks from the start of musical notes, noise gates attenuate signals that register below the threshold. You can achieve longer gate times(up to 10 secs) by typing in the text box instead of a slider.A Drawmer dual noise gate unit in a rackmountable format.Ī noise gate or gate is an electronic device or software that is used to control the volume of an audio signal. At the maximum gate may “Flutter” or “Snap.” The gate maximum (1000ms) the gate slowly opens(fades in) one second before the sound level goes past the threshold then gradually shuts (Fades out) after the audio level drops below the threshold for a second.

The gate minimum is 10ms, and it may open fully then close almost instantly as the audio level crosses the threshold.

If the setting is up to satisfaction, then apply Noise Gate to the whole song.

The default setting Level is – 12 dB, and it works well.

Once your threshold is correctly set, increase the “Level reduction” settings to the highest environment that produces a reasonable amount of gating.

Press CTRL + Z to undo if it is necessary to adjust the threshold level. However, you should easily hear if the threshold is set right. The gate is fully closed and produces an absolute silence when closed, and sound may be unnatural.

Use Noise Gate with these settings: Click on Function > Gate Level reduction > -100- Carefully listen to see that the noise is being cut, yet the audio is still present.

Choose a part of the audio track that has both sound and silence.

Click on Function > Analyze Noise level and take note of the suggested threshold level.

Open Noise Gate Effect and select noise only.
