# \&noisegate

Lowers your mic volume to 10% of its current value based on volume-level activity

Sender-Side Option! ([`&push`](/advanced-settings/setup-parameters/push.md))

## Aliases

* `&gating`
* `&gate`
* `&ng`

## Options

Example: `&noisegate=1`

| Value                   | Description                                                                |
| ----------------------- | -------------------------------------------------------------------------- |
| `0`                     | hides it from the menu                                                     |
| `1` \| (no value given) | enables the new noise gate (see Details)                                   |
| `2`                     | will mute the speakers when you are talking                                |
| `3`                     | will mute the speakers when someone else is talking (mainly for debugging) |
| `4`                     | will mute the microphone when someone else is speaking                     |

## Details

The default setting is OFF. You can switch on the noise gate in the audio settings:\

This is a new noise gate, that lowers your mic volume to 10% of its current value based on volume-level activity. If you haven't made a significant sound in few seconds, the noise gate kicks in, and will re-enable when a significant noise is detected. It will take about 300-ms for the volume to recover once the noise triggers it back on, which can be a small bit harsh/distracting at times.

The point of this feature is to allow guests who might be in a rather noisy room or who are unable to use echo cancellation to still engage with a chat, without them introducing feedback back into the room.

This is a very hard and aggressive noise filter, and a guest won't be audible to others in the room if others in the room are currently talking.

User feedback on this feature welcomed.

### Noise Gate Settings

[`&noisegatesettings`](/advanced-settings/audio-parameters/and-noisegatesettings.md) is used in conjunction with `&noisegate`. This feature lets you tweak the noise-gate's variables, making it more or less aggressive as needed.

It takes a comma separated list:

* First value is the closed-gate target gain as a percentage of normal volume. The code accepts 0 to 100. Use 0 to 40 for noticeable ducking; use 0 to 3 for near-mute.
* Second value is the threshold value where the gate is triggered if below it. \~ 100 is loudly speaking, \~ 20 is light background noise levels, and under 5 is quiet background levels.
* Third value is how sticky the gate-open position is, in milliseconds. The current implementation checks this in 100-ms steps, so use multiples of 100 ms. For example, `3000` means about 3 seconds.

Example:\
[`https://vdo.ninja/alpha/?noisegate&noisegatesettings=10,25,3000`](https://vdo.ninja/alpha/?noisegate\&noisegatesettings=10,25,3000)

To help users with testing the noise gate and configuring the noise gate settings, there's an interactive page here for it: <https://vdo.ninja/noisegate>

{% hint style="warning" %}
The `/noisegate` test page uses a classic DAW-style 5-parameter format. Its output string is **not** directly compatible with the `&noisegatesettings` URL parameter, which uses the 3-value internal format. See [`&noisegatesettings`](/advanced-settings/audio-parameters/and-noisegatesettings.md) for the correct format.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.vdo.ninja/advanced-settings/audio-parameters/noisegate.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
