# Reducing Background Noise (Noise Suppressor)

## Reducing Background Noise (Noise Suppressor)

{% tabs %}
{% tab title="English" %}

### Clean up your mic sound

Noise Suppressor cleans up your microphone so viewers hear your voice clearly — not the keyboard clatter, fan hum, or other background noise around you.

> **Android only**: This feature is available on **Android 5.3.0 or later**. It is not available on iOS.

### Turning it on

You can switch Noise Suppressor on or off from two places, and they stay in sync:

**From the More menu**

1. During broadcast setup or your live, tap the **More (⋯)** menu.
2. Tap **Noise suppressor** to turn it on or off.

**From the Audio Mixer**

1. Open the **Audio Mixer**.
2. Under **Voice effect**, toggle **Noise suppressor** on or off.

It is **off by default**. Once you turn it on, PRISM remembers your choice — even after you switch microphones, end a live, or restart the app. (Reinstalling the app resets it.)

### Good to know

* Noise Suppressor removes noise from **your microphone** before it reaches viewers. This is different from the noise cancelling on your earphones, which only changes what **you** hear.
* It sits in the same **Voice effect** group as Voice Changer, so you can combine it with your other audio settings.

### 마이크 소리를 깔끔하게

잡음 억제를 켜면 마이크 소리를 깔끔하게 다듬어, 키보드 소리·선풍기 소리·주변 소음 대신 여러분의 목소리가 또렷하게 전달됩니다.

> **Android 전용**: 이 기능은 **Android 5.3.0 이상**에서 사용할 수 있습니다. iOS에서는 제공되지 않습니다.

### 켜는 방법

잡음 억제는 두 곳에서 켜고 끌 수 있으며, 두 설정은 서로 연동됩니다.

**더보기 메뉴에서**

1. 방송 준비 중이나 라이브 중에 **더보기(⋯)** 메뉴를 탭합니다.
2. **잡음 억제**를 탭해 켜거나 끕니다.

**오디오 믹서에서**

1. **오디오 믹서**를 엽니다.
2. **음성 효과** 아래의 **잡음 억제** 스위치를 켜거나 끕니다.

기본값은 **꺼짐**입니다. 한 번 켜 두면 마이크를 바꾸거나, 라이브를 종료하거나, 앱을 다시 실행해도 설정이 유지됩니다. (앱을 삭제하면 초기화됩니다.)

### 알아두면 좋아요

* 잡음 억제는 시청자에게 소리가 나가기 전에 **내 마이크** 소리에서 잡음을 없앱니다. 내 귀에 들리는 소음을 줄이는 이어폰의 노이즈 캔슬링과는 다릅니다.
* 음성 변환과 같은 **음성 효과** 그룹에 있어, 다른 오디오 설정과 함께 사용할 수 있습니다.

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://guide.prismlive.com/mobile/guides/features/others/reducing-background-noise-noise-suppressor.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
