You may have to tweak it a bit (normally rounding it down a bit) to get it to work perfectly.Finally set the Threshold value to the previous Average RMS Amplitude value we found out before.(Make sure you have the correct preset selected, normally Default is the way to go depending on what you want to do) In the Dynamics window you’ll want to enable AutoGate which is what the Noise Gate is called in Adobe Audition.Go to the Effects pane at the top and expand Amplitude and Compression submenu and click Dynamics.Next, is time to add the noise gate effect onto the audio channel. The one we are interested in is Average RMS Amplitude. This will analyze the selection and return a bunch of statistics from the sample.

Note: All noise gate software plugins will have the four parameters described above. Chatter occurs when there is a high-speed change in signal level causing continuous gate opening and closing. You can manually set it or use the default minimum of 20 to 30ms, preventing chatter. The hold is the minimum time the gate remains open. When used as an effect, a higher value is preferred to close the gate quickly. If you use the gate to remove noise, a low value would be ideal for creating a natural decay. It can be in milliseconds or seconds, depending on the purpose of the gate. The release states the time taken to close the gate. It is best to use slow attack times of above 10ms for vocals or speech and higher times for percussive instruments. To remove the click sound, increase the attack time until it disappears. Slow signals require a high attack time to open the gate slowly otherwise, a low attack time can generate a click sound. The attack is the time taken (in milliseconds) to open the gate. A low threshold allows more sound to pass through the gate once opened. A high threshold implies that a strong or loud sound signal is required to open the gate. ThresholdĮngineer Beau Brown labels the threshold as “the key to the gate.” It is a decibel level that describes when the gate should open or close.

When the sound is above or louder than the threshold, the gate opens, allowing the sound to pass through the audio channel. The gate closes when the sound is below the threshold set, blocking it. Gates are of different designs, but all operate similarly.Ī noise gate uses a noise threshold that you set manually to block sound signals passing through an audio channel.

Here, we examine how noise gates work and how you can use them to clean up light background noises from your audio recordings. You can use a gate or noise gate to enhance the quality of your recorded podcast or other audio-like music by blocking unwanted sounds or controlling them to your desired levels.
The best option is to minimize the unwanted sound and manage it during post-production. It is difficult to eliminate background noise even when recording in a treated room or quiet environment when recording audio.
