# AI Noise Suppression (/en/realtime-media/marketplace/build/add-audio-effects/ains/android)

> For AI agents: see the complete documentation index at [llms.txt](/llms.txt).

AI Noise Suppression enables you to suppress hundreds of types of noise and reduce distortion in human voices when multiple people speak at the same time. In use-cases such as online meetings, online chat rooms, video consultations with doctors, and online gaming, AI Noise Suppression makes virtual communication as smooth as face-to-face interaction.

    AI Noise Suppression reduces the following types of noise:

    * Television
    * Kitchen
    * Street, such as birds chirping, traffic, and subway sounds
    * Machine, such as fans, air conditioners, vacuum cleaners, and copiers
    * Office, such as keyboard and mouse clicks
    * Household, such as doors opening, creaking chairs, crying babies, and house renovations
    * Constant knocking
    * Beeps and clapping
    * Music

    You can choose following noise reduction strategies:

    * Default: Reduces noise to a comfortable level without distorting human voice.
    * Custom: A more enhanced or customized noise reduction strategy for your business use-case. Contact [support@agora.io](mailto\:support@agora.io) for details.

    ## Prerequisites [#prerequisites]

    Ensure that you have implemented the [SDK quickstart](../../index.mdx) in your project.

    ## Enable AI Noise Suppression [#enable-ai-noise-suppression]

    This section shows you how to integrate AI Noise Suppression into your app.

    Call `setAINSMode` to enable the AI noise suppression feature, and select a noise suppression mode:

    <CodeBlockTabs defaultValue="java">
      <CodeBlockTabsList>
        <CodeBlockTabsTrigger value="java">
          Java
        </CodeBlockTabsTrigger>

        <CodeBlockTabsTrigger value="kotlin">
          Kotlin
        </CodeBlockTabsTrigger>
      </CodeBlockTabsList>

      <CodeBlockTab value="java">
        ```java
        // Noise reductions modes
        // 0 -> Balance mode
        // 1 -> Aggressive mode
        // 2 -> Aggressive mode with low latency
        int mode = 1;
        // Set the mode for Audio AI Noise Suppression
        int result = rtcEngine.setAINSMode(true, mode);
        ```
      </CodeBlockTab>

      <CodeBlockTab value="kotlin">
        ```kotlin
        // Noise reductions modes
        // 0 -> Balance mode
        // 1 -> Aggressive mode
        // 2 -> Aggressive mode with low latency
        val mode = 1
        // Set the mode for Audio AI Noise Suppression
        val result = rtcEngine.setAINSMode(true, mode)
        ```
      </CodeBlockTab>
    </CodeBlockTabs>
