```

--------------------------------

### Install Project Dependencies

Source: https://github.com/volcengine/volcenginertc/blob/main/Web/QuickStart_Demo/BasicDemo/README.md

Installs all the necessary dependencies for the demo project using Yarn. Run this command in the project's root directory.

```bash
yarn
```

--------------------------------

### Install Yarn Globally

Source: https://github.com/volcengine/volcenginertc/blob/main/Web/QuickStart_Demo/BasicDemo/README.md

Installs the Yarn package manager globally on your system. This is a prerequisite for managing project dependencies and running the demo.

```bash
npm install -g yarn
```

--------------------------------

### Clone VolcEngineRTC Project

Source: https://github.com/volcengine/volcenginertc/blob/main/iOS/README.md

Clone the VolcEngineRTC project from GitHub to access the iOS example project. Ensure you checkout the main branch.

```bash
git clone https://github.com/volcengine/VolcEngineRTC.git
cd VolcEngineRTC
git checkout main
```

--------------------------------

### Start Internal Audio Capture

Source: https://github.com/volcengine/volcenginertc/blob/main/Web/Advanced_Demo/Examples/aians/README.md

Initiate the internal audio capture process using the RTC engine. This is a prerequisite for the AI noise reduction to process audio.

```typescript
// 开启内部音频采集
engine.startAudioCapture();
```

--------------------------------

### Configure AppID and AppKey

Source: https://github.com/volcengine/volcenginertc/blob/main/iOS/README.md

Open the ApiExample.xcworkspace in Xcode. Obtain your AppID and AppKey from the VolcEngine console and update the kAppID and kAppKey constants in ApiExample/Config.swift. Incorrect values will prevent compilation.

```swift
let kAppID = "YOUR_APP_ID"
let kAppKey = "YOUR_APP_KEY"
```

--------------------------------

### Configure Signing & Capabilities

Source: https://github.com/volcengine/volcenginertc/blob/main/iOS/README.md

In Xcode, select the ApiExample project and go to the Signing & Capabilities tab. Enable 'Automatically manage signing' or manually configure your developer certificate. Ensure your Team is set to 'Personal Team' and update the Bundle Identifier to a unique value.

```swift
Bundle Identifier: rtc.vertcdemo.apiexample.dev (or your custom identifier)
```

--------------------------------

### Demo Configuration Object

Source: https://github.com/volcengine/volcenginertc/blob/main/Web/QuickStart_Demo/BasicDemo/README.md

This JavaScript object holds the configuration for the demo, including AppId, RoomId, and a list of user tokens. Ensure these values match those used for token generation.

```javascript
const config = {
  appId: 'yourAppId',
  roomId: 'yourRoomId',
  tokens: [
    {
      userId: 'yourUserId1',
      token: 'yourToken1',
    },
    {
      userId: 'yourUserId2',
      token: 'yourToken2',
    }
  ],
};
```

--------------------------------

### Set VolcBeauty License Name

Source: https://github.com/volcengine/volcenginertc/blob/main/iOS/README.md

Obtain the license file for intelligent beautification effects. Place the certificate file in the ApiExample/ImportantComponents/Beauty/VolcBeauty/resource folder. Update the CVLicenseName constant in ApiExample/Config.swift with the exact filename of your certificate.

```swift
let CVLicenseName = "rtc_test_vertc.veRTCDemo.ios_4.4.2_633.licbag"
```

--------------------------------

### Import AI Noise Reduction Plugin

Source: https://github.com/volcengine/volcenginertc/blob/main/Web/Advanced_Demo/Examples/aians/README.md

Import the RTCAIAnsExtension class from the Volcengine RTC SDK. This is the first step to using the AI noise reduction functionality.

```typescript
import RTCAIAnsExtension from '@volcengine/rtc/extension-ainr';
```

--------------------------------

### Embed Effect SDK Framework

Source: https://github.com/volcengine/volcenginertc/blob/main/iOS/README.md

Download the RTC SDK iOS offline package. Extract the 'effect-sdk.framework' file and place it in the ApiExample/ImportantComponents/Beauty/VolcBeauty folder. Ensure it is set to 'Embed & Sign' under Frameworks, Libraries, and Embedded Content in Xcode's General settings.

```swift
// Ensure effect-sdk.framework is set to Embed & Sign
```

--------------------------------

### Replace FaceUnity Beauty Authpack

Source: https://github.com/volcengine/volcenginertc/blob/main/iOS/README.md

For FaceUnity beauty effects, contact their business team for a certificate. Replace the existing 'authpack.h' file in the ApiExample/ImportantComponents/Beauty/FaceUnityBeauty directory with the certificate you received.

```c
// Replace ApiExample/ImportantComponents/Beauty/FaceUnityBeauty/authpack.h with your certificate
```

--------------------------------

### Register AI Noise Reduction Plugin

Source: https://github.com/volcengine/volcenginertc/blob/main/Web/Advanced_Demo/Examples/aians/README.md

Instantiate the AIAnsExtension and register it with the RTC engine. Ensure the engine instance is created with your App ID. Error handling is included for registration failures.

```typescript
import VERTC from '@volcengine/rtc';
// 创建引擎实例
const engine = VERTC.createEngine('appid');

// 创建 AI 降噪插件实例
const AIAnsExtension = new RTCAIAnsExtension();
// 注册 AI 降噪插件
try {
  await engine.registerExtension(AIAnsExtension);
} catch (error) {
  // 注册失败，详细信息：error.message
}
```

--------------------------------

### IRTCAIAnsExtension API Reference

Source: https://github.com/volcengine/volcenginertc/blob/main/Web/Advanced_Demo/Examples/aians/README.md

Reference for the IRTCAIAnsExtension class, which provides methods to control AI noise suppression.

```APIDOC
## IRTCAIAnsExtension

Type: `class`

### enable

Type: `() => void`

Description: Enables AI noise suppression. This applies to internally captured audio.

### disable

Type: `() => void`

Description: Disables AI noise suppression.
```

--------------------------------

### Enable and Disable AI Noise Reduction

Source: https://github.com/volcengine/volcenginertc/blob/main/Web/Advanced_Demo/Examples/aians/README.md

Control the AI noise reduction feature by calling enable() to turn it on and disable() to turn it off. These methods operate on the AIAnsExtension instance.

```typescript
// 开启/关闭降噪
AIAnsExtension.enable();
AIAnsExtension.disable();
```
