# App size optimization (/en/realtime-media/broadcast-streaming/build/optimize-quality-and-connection/app-size-optimization) > For AI agents: see the complete documentation index at [llms.txt](/llms.txt). <_PlatformTabsGroup groupMode="structured" canonicalPlatform="web" platforms="["android","ios","macos","web","windows","electron","flutter","react-native","unity"]" showTabs="true"> <_PlatformPanel platform="android"> <_PlatformProcessedMarker groupMode="structured" canonicalPlatform="web" platform="android" /> Reducing the app size is of great significance in improving user experience. A smaller package size means that users consume less bandwidth and time to download the app. Consider the following use-cases where app size optimization is critical: * There are strict requirements on the size of the app. For example, running the app on smart wearable devices with limited storage space. * The target user group of the app is located in underdeveloped areas. The poor network connectivity causes the app download time to be too long. This page shows you how to optimize the size of apps with integrated Video SDK. ### Use the Lite SDK [#use-the-lite-sdk] Since version 4.4.0, Agora offers a Lite SDK that provides basic audio and video call functions in a smaller package size. If you only need to implement basic audio and video call functions, integrate the Lite SDK. For details see [SDKs](../../../sdks). The Lite SDK includes only the following extensions: * Video encoding extension * Video decoding extension Other extensions and related functions in the [Extension list](#extension-list) are not supported. ### Use the Voice SDK [#use-the-voice-sdk] Video SDK supports both audio and video functions, and the package size is large. If you only need to use audio features, best practice is to integrate the [Voice SDK](../../../sdks). For details, see [Voice SDK Quickstart](/en/realtime-media/voice/quickstart). ### Remove unnecessary extensions [#remove-unnecessary-extensions] Video SDK provides optional extension dynamic libraries. The name of the extension is suffixed with `extension`. See the [extension list](#extension-list) for details on the function and size of the extensions. Refer to the following ways to exclude these extensions to reduce the size of the app. #### Remove extensions when integrating manually [#remove-extensions-when-integrating-manually] When integrating through the [Direct download](../../../sdks) link, manually delete the extension files that you do not need to use. #### Remove extensions when integrating using Maven Central [#remove-extensions-when-integrating-using-maven-central] When integrating the Android SDK through Maven Central, you can modify the `/Gradle Scripts/build.gradle(Module: .app)` file to specify the dynamic libraries you need to integrate and exclude extensions you do not need to use. For details on the correspondence between each file in the Android SDK and the fields in `dependencies`, see [implementation fields](#implementation-fields) for details. Refer to the following samples to include, all, none, or selected extensions. **Use all extensions** ```js dependencies { implementation 'io.agora.rtc:full-sdk:4.0.1' implementation 'io.agora.rtc:full-screen-sharing:4.0.1' // ... } ``` **Don** ```js dependencies { implementation 'io.agora.rtc:full-rtc-basic:4.0.1' //... } ``` **Use selected extensions** ```js dependencies { def agora_sdk_version = "4.3.0" // The following code contains $, so you must use double-quotes implementation "io.agora.rtc:full-rtc-basic:\${agora_sdk_version}" implementation "io.agora.rtc:full-ains:\${agora_sdk_version}" implementation "io.agora.rtc:audio-beauty:\${agora_sdk_version}" //... } ``` ## Reference [#reference] This section contains content that completes the information in this page, or points you to documentation that explains other aspects to this product. ### Extension list [#extension-list] Refer to the following information for an introduction to each Video SDK extension and the increase in the size of your app after integration. The information in this section is based on version 4.4.0 of the Video SDK. **AI Noise Suppression** The Video SDK supports a new version of AI noise suppression, which provides better vocal fidelity, cleaner noise suppression, and adds de-reverberation capabilities.

A smaller package size means that users consume less bandwidth and time to download the app. Consider the following use-cases where app size optimization is critical: * There are strict requirements on the size of the app. For example, running the app on smart wearable devices with limited storage space. * The target user group of the app is located in underdeveloped areas. The poor network connectivity causes the app download time to be too long. This page shows you how to optimize the size of apps with integrated Video SDK. ### Use the Lite SDK [#use-the-lite-sdk-1] Since version 4.4.0, Agora offers a Lite SDK that provides basic audio and video call functions in a smaller package size. If you only need to implement basic audio and video call functions, integrate the Lite SDK. For details see [SDKs](../../../sdks). The Lite SDK includes only the following extensions: * Video encoding extension * Video decoding extension Other extensions and related functions in the [Extension list](#extension-list) are not supported. ### Use the Voice SDK [#use-the-voice-sdk-1] Video SDK supports both audio and video functions, and the package size is large. If you only need to use audio features, best practice is to integrate the [Voice SDK](../../../sdks). For details, see [Voice SDK Quickstart](/en/realtime-media/voice/quickstart). ### Remove unnecessary extensions [#remove-unnecessary-extensions-1] Video SDK provides optional extension dynamic libraries. The name of the extension is suffixed with `extension`. See the [extension list](#extension-list) for details on the function and size of the extensions. Refer to the following ways to exclude these extensions to reduce the size of the app. #### Delete extensions when integrating using CocoaPods [#delete-extensions-when-integrating-using-cocoapods] When integrating the iOS or macOS SDK through CocoaPods, use the `subspecs` field in the Podfile to specify the dynamic libraries you need to integrate. This excludes extensions you do not need. For details about the corresponding relationship between dynamic libraries and `subspecs` field, see [subspecs field](#subspecs-field). Refer to the following samples to use all, none, or some extensions: **Use all extensions** ```ruby # platform :ios, '9.0' target 'Your App' do pod 'AgoraRtcEngine_iOS', '4.3.1' end ``` **Don** ```ruby # platform :ios, '9.0' target 'Your App' do pod 'AgoraRtcEngine_iOS', '4.3.1', :subspecs => ['RtcBasic'] end ``` **Use some extensions** ```ruby # platform :ios, '9.0' target 'Your App' do pod 'AgoraRtcEngine_iOS', '4.3.1', :subspecs => ['RtcBasic', 'AINS', 'AudioBeauty'] end ``` When using the above pod command, make sure that the SDK version you specify includes the extension you have selected, and that the `subspecs` field is correct, otherwise a pod installation error is reported. For example, if you use `pod 'AgoraRtcEngine_iOS', '4.0.0', :subspecs => ['RtcBasic', 'AgoraRtcAINS']`, an error is reported. ## Reference [#reference-1] This section contains content that completes the information in this page, or points you to documentation that explains other aspects to this product. ### Extension list [#extension-list-1] Refer to the following information for an introduction to each Video SDK extension and the increase in the size of your app after integration. The information in this section is based on version 4.4.0 of the Video SDK. **AI Noise Suppression** The Video SDK supports a new version of AI noise suppression, which provides better vocal fidelity, cleaner noise suppression, and adds de-reverberation capabilities.

A smaller package size means that users consume less bandwidth and time to download the app. Consider the following use-cases where app size optimization is critical: * There are strict requirements on the size of the app. For example, running the app on smart wearable devices with limited storage space. * The target user group of the app is located in underdeveloped areas. The poor network connectivity causes the app download time to be too long. This page shows you how to optimize the size of apps with integrated Video SDK. ### Remove unnecessary extensions [#remove-unnecessary-extensions-2] Video SDK provides optional extension dynamic libraries. The name of the extension is suffixed with `extension`. See the [extension list](#extension-list) for details on the function and size of the extensions. Refer to the following ways to exclude these extensions to reduce the size of the app. #### Delete extensions when integrating using CocoaPods [#delete-extensions-when-integrating-using-cocoapods-1] When integrating the iOS or macOS SDK through CocoaPods, use the `subspecs` field in the Podfile to specify the dynamic libraries you need to integrate. This excludes extensions you do not need. For details about the corresponding relationship between dynamic libraries and `subspecs` field, see [subspecs field](#subspecs-field). Refer to the following samples to use all, none, or some extensions: **Use all extensions** ```ruby # platform :ios, '9.0' target 'Your App' do pod 'AgoraRtcEngine_macOS', '4.3.1' end ``` **Don** ```ruby # platform :ios, '9.0' target 'Your App' do pod 'AgoraRtcEngine_macOS', '4.3.1', :subspecs => ['RtcBasic'] end ``` **Use some extensions** ```ruby # platform :ios, '9.0' target 'Your App' do pod 'AgoraRtcEngine_macOS', '4.3.1', :subspecs => ['RtcBasic', 'AINS', 'AudioBeauty'] end ``` When using the above pod command, make sure that the SDK version you specify includes the extension you have selected, and that the `subspecs` field is correct, otherwise a pod installation error is reported. For example, if you use `pod 'AgoraRtcEngine_iOS', '4.0.0', :subspecs => ['RtcBasic', 'AgoraRtcAINS']`, an error is reported. ## Reference [#reference-2] This section contains content that completes the information in this page, or points you to documentation that explains other aspects to this product. ### Extension list [#extension-list-2] Refer to the following information for an introduction to each Video SDK extension and the increase in the size of your app after integration. The information in this section is based on version 4.4.0 of the Video SDK. **AI Noise Suppression** The Video SDK supports a new version of AI noise suppression, which provides better vocal fidelity, cleaner noise suppression, and adds de-reverberation capabilities.

A smaller package size means that users consume less bandwidth and time to download the app. Consider the following use-cases where app size optimization is critical: * There are strict requirements on the size of the app. For example, running the app on smart wearable devices with limited storage space. * The target user group of the app is located in underdeveloped areas. The poor network connectivity causes the app download time to be too long. This page shows you how to optimize the size of apps with integrated Video SDK. ## Reduce the app size [#reduce-the-app-size] To reduce the app size, implement the following strategies: ### Use tree shaking [#use-tree-shaking] In versions before v4.19.0, the `AgoraRTC` module is the entrance to all callable methods in the Web Video SDK. Even if you only use a part of the Video SDK's functionality, you still need to load the complete SDK, which may result in the app containing a lot of unused code. Starting from version 4.19.0, the Video SDK for Web has integrated [tree shaking](https://webpack.js.org/guides/tree-shaking/) support. Using tree shaking has the following advantages: * Only load the SDK features you actually use, unreferenced code is removed during the build process. * Reduce redundancy between SDK dependencies and your app dependencies. Starting from version 4.22.0, in addition to the core modules, the SDK also provides multiple independent service modules for optional use, such as media stream relay and live streaming, to meet the needs of different business use-cases. The optimization effect of tree shaking is currently limited by the SDK architecture. Agora will continue to improve the tree shaking effect in future versions. To use tree shaking, follow these steps to integrate the SDK: 1. Run the following command to install the latest SDK package using npm: ```bash npm install agora-rtc-sdk-ng ``` 2. Import all used methods, enumerations, constants, types, and so on by adding `/esm` at the end of the package name `agora-rtc-sdk-ng`: ```javascript // Example of correct reference citation method import { createClient } from "agora-rtc-sdk-ng/esm"; // Import enum import { ConnectionDisconnectedReason } from "agora-rtc-sdk-ng/esm"; // Import constant import { VERSION } from "agora-rtc-sdk-ng/esm"; // Import type import type { ICameraVideoTrack } from "agora-rtc-sdk-ng/esm"; ``` 3. Starting from version 4.23.0, you can integrate the functional modules you need as follows: **Plan B** ```js // Import core module import { AgoraRTC } from "agora-rtc-sdk-ng/esm"; // Import Plan-B module import { PlanBConnectionService } from "agora-rtc-sdk-ng/services/planb-connection"; AgoraRTC.use(PlanBConnectionService); ``` **Content moderation** ```js // Import core module import { AgoraRTC } from "agora-rtc-sdk-ng/esm"; // Import real-time moderation (content moderation) module import { ImageModerationService } from "agora-rtc-sdk-ng/services/image-moderation"; import { ContentInspectService } from "agora-rtc-sdk-ng/services/content-inspect"; AgoraRTC.use(ImageModerationService) .use(ContentInspectService); ``` **Channel media relay** ```js // Import core module import { AgoraRTC } from "agora-rtc-sdk-ng/esm"; // Import cross-channel media relay module import { ChannelMediaRelayService } from "agora-rtc-sdk-ng/services/channel-media-relay"; AgoraRTC.use(ChannelMediaRelayService); ``` **Live streaming** ```js // Import core module import { AgoraRTC } from "agora-rtc-sdk-ng/esm"; // Import live streaming service module import { LiveStreamingService } from "agora-rtc-sdk-ng/services/live-streaming"; AgoraRTC.use(LiveStreamingService); ``` ## Reference [#reference-3] This section contains content that completes the information in this page, or points you to documentation that explains other aspects to this product. ### Frequently asked questions [#frequently-asked-questions-3] * [Why are dynamic libraries preferred over static libraries in the Video SDK](/en/api-reference/faq/integration/dynamic_or_static_library) <_PlatformProcessedMarker close="true" /> <_PlatformPanel platform="windows"> <_PlatformProcessedMarker groupMode="structured" canonicalPlatform="web" platform="windows" /> Reducing the app size is of great significance in improving user experience.

A smaller package size means that users consume less bandwidth and time to download the app. Consider the following use-cases where app size optimization is critical: * There are strict requirements on the size of the app. For example, running the app on smart wearable devices with limited storage space. * The target user group of the app is located in underdeveloped areas. The poor network connectivity causes the app download time to be too long. This page shows you how to optimize the size of apps with integrated Video SDK. ### Use the Voice SDK [#use-the-voice-sdk-2] Video SDK supports both audio and video functions, and the package size is large. If you only need to use audio features, best practice is to integrate the [Voice SDK](../../../sdks). For details, see [Voice SDK Quickstart](/en/realtime-media/voice/quickstart). ### Remove unnecessary extensions [#remove-unnecessary-extensions-4] Video SDK provides optional extension dynamic libraries. The name of the extension is suffixed with `extension`. See the [extension list](#extension-list) for details on the function and size of the extensions. Refer to the following ways to exclude these extensions to reduce the size of the app. #### Remove extensions when integrating manually [#remove-extensions-when-integrating-manually-1] When integrating through the [Direct download](../../../sdks) link, manually delete the extension files that you do not need to use. ## Reference [#reference-5] This section contains content that completes the information in this page, or points you to documentation that explains other aspects to this product. ### Extension list [#extension-list-4] Refer to the following information for an introduction to each Video SDK extension and the increase in the size of your app after integration.

A smaller package size means that users consume less bandwidth and time to download the app. Consider the following use-cases where app size optimization is critical: * There are strict requirements on the size of the app. For example, running the app on smart wearable devices with limited storage space. * The target user group of the app is located in underdeveloped areas. The poor network connectivity causes the app download time to be too long. This page shows you how to optimize the size of apps with integrated Video SDK. ### Remove unnecessary extensions [#remove-unnecessary-extensions-5] Video SDK provides optional extension dynamic libraries. The name of the extension is suffixed with `extension`. See the [extension list](#extension-list) for details on the function and size of the extensions. Refer to the following ways to exclude these extensions to reduce the size of the app. Android iOS and macOS If your target platform is Android, use Gradle's `packagingOptions.exclude` properties to exclude unnecessary extension dynamic libraries from the final `APK` or `AAR` file. Removing these files during the packaging process reduces the app size and improves app performance. In the `build.gradle` file in the project root directory, find the `android` configuration block. Under the module `packagingOptions`, use the `exclude` attribute to specify the extension dynamic libraries you want to exclude. Refer to the following example to exclude specific extensions: ```text android { // ... packagingOptions { // Exclude AI denoise extension for the armeabi-v7a architecture exclude 'lib/armeabi-v7a/libagora_ai_denoise_extension.so' // Exclude AI denoise extension for the arm64-v8a architecture exclude 'lib/arm64-v8a/libagora_ai_denoise_extension.so' // Exclude spatial audio extension for the armeabi-v7a architecture exclude 'lib/armeabi-v7a/libagora_spatial_audio_extension.so' // Exclude spatial audio extension for the arm64-v8a architecture exclude 'lib/arm64-v8a/libagora_spatial_audio_extension.so' } } ``` If your target platform is iOS or macOS, follow these steps to reduce the size of your app: 1. Add the following script to the Podfile under the target section for the `agora_rtc_engine` dependency. This script marks unnecessary extensions as [weak frameworks](https://guides.cocoapods.org/syntax/podspec.html#weak_frameworks): ```ruby post_install do |installer| installer.pods_project.targets.each do |target| flutter_additional_ios_build_settings(target) targets_to_weaklink=['Pods-Runner', "agora_rtc_engine"] # Add more -weak_framework flags for other unnecessary extensions if needed frameworks_to_weaklink=["AgoraAiEchoCancellationExtension", "AgoraAiNoiseSuppressionExtension", "AgoraAudioBeautyExtension", "AgoraClearVisionExtension", "AgoraContentInspectExtension", "AgoraDrmLoaderExtension", "AgoraReplayKitExtension", "AgoraSpatialAudioExtension ", "AgoraSuperResolutionExtension", "AgoraVideoQualityAnalyzerExtension", "AgoraVideoSegmentationExtension"] next unless targets_to_weaklink.include?(target.name) target.build_configurations.each do |config| base_config_reference = config.base_configuration_reference unless base_config_reference. nil? xcconfig_path = base_config_reference.real_path xcconfig = File.read(xcconfig_path) frameworks_to_weaklink.each do |framework| xcconfig = xcconfig.gsub(/-framework "#{framework}"/, "-weak_framework \"#{framework}\"") end File.open(xcconfig_path, "w") { |file| file << xcconfig } end end end end ``` 2. To remove unnecessary extensions, follow these steps in Xcode: 3. Navigate to the **Build Phases** tab. 4. Click the `+` button at the bottom left corner of the **Build Phases** tab and select **New Run Script Phase**. 5. Specify Shell as `/usr/bin/ruby` and replace the code part with the following script: ```bash $stderr.puts "Removing Unnecessary Frameworks" # The extensions listed in frameworks_to_weaklink here should match those in Step 1. frameworks_to_weaklink=["AgoraAiEchoCancellationExtension", "AgoraAiNoiseSuppressionExtension", "AgoraAudioBeautyExtension", "AgoraClearVisionExtension", "AgoraContentInspectExtension", "AgoraDrmLoaderExtension", "AgoraReplayKitExtension", "AgoraSpatialAudioExtension ", "AgoraSuperResolutionExtension", "AgoraVideoQualityAnalyzerExtension", "AgoraVideoSegmentationExtension"] for framework in frameworks_to_weaklink framework_path = "#{ENV['BUILT_PRODUCTS_DIR']}/#{ENV['FRAMEWORKS_FOLDER_PATH']}/#{framework}.framework" `rm -Rf "#{framework_path}"` end ``` The following figure shows the required steps: ![reduce app size step 2](https://assets-docs.agora.io/images/video-sdk/reduce-app-size-flutter-step-2.png) ## Reference [#reference-6] This section contains content that completes the information in this page, or points you to documentation that explains other aspects to this product. ### Extension list [#extension-list-5] Refer to the following information for an introduction to each Video SDK extension and the increase in the size of your app after integration.

A smaller package size means that users consume less bandwidth and time to download the app. Consider the following use-cases where app size optimization is critical: * There are strict requirements on the size of the app. For example, running the app on smart wearable devices with limited storage space. * The target user group of the app is located in underdeveloped areas. The poor network connectivity causes the app download time to be too long. This page shows you how to optimize the size of apps with integrated Video SDK. ### Remove unnecessary extensions [#remove-unnecessary-extensions-6] Video SDK provides optional extension dynamic libraries. The name of the extension is suffixed with `extension`. See the [extension list](#extension-list) for details on the function and size of the extensions. Refer to the following ways to exclude these extensions to reduce the size of the app. Android iOS and macOS If your target platform is Android, use Gradle's `packagingOptions.exclude` properties to exclude unnecessary extension dynamic libraries from the final `APK` or `AAR` file. Removing these files during the packaging process reduces the app size and improves app performance. In the `build.gradle` file in the project root directory, find the `android` configuration block. Under the module `packagingOptions`, use the `exclude` attribute to specify the extension dynamic libraries you want to exclude. Refer to the following example to exclude specific extensions: ```text android { // ... packagingOptions { // Exclude AI denoise extension for the armeabi-v7a architecture exclude 'lib/armeabi-v7a/libagora_ai_denoise_extension.so' // Exclude AI denoise extension for the arm64-v8a architecture exclude 'lib/arm64-v8a/libagora_ai_denoise_extension.so' // Exclude spatial audio extension for the armeabi-v7a architecture exclude 'lib/armeabi-v7a/libagora_spatial_audio_extension.so' // Exclude spatial audio extension for the arm64-v8a architecture exclude 'lib/arm64-v8a/libagora_spatial_audio_extension.so' } } ``` If your target platform is iOS or macOS, follow these steps to reduce the size of your app: 1. Add the following script to the Podfile under the target section for the `agora_rtc_engine` dependency. This script marks unnecessary extensions as [weak frameworks](https://guides.cocoapods.org/syntax/podspec.html#weak_frameworks): ```ruby post_install do |installer| installer.pods_project.targets.each do |target| flutter_additional_ios_build_settings(target) targets_to_weaklink=['Pods-Runner', "agora_rtc_engine"] # Add more -weak_framework flags for other unnecessary extensions if needed frameworks_to_weaklink=["AgoraAiEchoCancellationExtension", "AgoraAiNoiseSuppressionExtension", "AgoraAudioBeautyExtension", "AgoraClearVisionExtension", "AgoraContentInspectExtension", "AgoraDrmLoaderExtension", "AgoraReplayKitExtension", "AgoraSpatialAudioExtension ", "AgoraSuperResolutionExtension", "AgoraVideoQualityAnalyzerExtension", "AgoraVideoSegmentationExtension"] next unless targets_to_weaklink.include?(target.name) target.build_configurations.each do |config| base_config_reference = config.base_configuration_reference unless base_config_reference. nil? xcconfig_path = base_config_reference.real_path xcconfig = File.read(xcconfig_path) frameworks_to_weaklink.each do |framework| xcconfig = xcconfig.gsub(/-framework "#{framework}"/, "-weak_framework \"#{framework}\"") end File.open(xcconfig_path, "w") { |file| file << xcconfig } end end end end ``` 2. To remove unnecessary extensions, follow these steps in Xcode: 3. Navigate to the **Build Phases** tab. 4. Click the `+` button at the bottom left corner of the **Build Phases** tab and select **New Run Script Phase**. 5. Specify Shell as `/usr/bin/ruby` and replace the code part with the following script: ```bash $stderr.puts "Removing Unnecessary Frameworks" # The extensions listed in frameworks_to_weaklink here should match those in Step 1. frameworks_to_weaklink=["AgoraAiEchoCancellationExtension", "AgoraAiNoiseSuppressionExtension", "AgoraAudioBeautyExtension", "AgoraClearVisionExtension", "AgoraContentInspectExtension", "AgoraDrmLoaderExtension", "AgoraReplayKitExtension", "AgoraSpatialAudioExtension ", "AgoraSuperResolutionExtension", "AgoraVideoQualityAnalyzerExtension", "AgoraVideoSegmentationExtension"] for framework in frameworks_to_weaklink framework_path = "#{ENV['BUILT_PRODUCTS_DIR']}/#{ENV['FRAMEWORKS_FOLDER_PATH']}/#{framework}.framework" `rm -Rf "#{framework_path}"` end ``` The following figure shows the required steps: ![reduce app size step 2](https://assets-docs.agora.io/images/video-sdk/reduce-app-size-flutter-step-2.png) ## Reference [#reference-7] This section contains content that completes the information in this page, or points you to documentation that explains other aspects to this product. ### Extension list [#extension-list-6] Refer to the following information for an introduction to each Video SDK extension and the increase in the size of your app after integration.

A smaller package size means that users consume less bandwidth and time to download the game. Consider the following use-cases where app size optimization is critical: * There are strict requirements on the size of the game. For example, running the game on smart wearable devices with limited storage space. * The target user group of the game is located in underdeveloped areas. The poor network connectivity causes the game download time to be too long. This page shows you how to optimize the size of games with integrated Video SDK. ### Use the Voice SDK [#use-the-voice-sdk-3] Video SDK supports both audio and video functions, and the package size is large. If you only need to use audio features, best practice is to integrate the [Voice SDK](../../../sdks). For details, see [Voice SDK Quickstart](/en/realtime-media/voice/quickstart). ### Remove unnecessary extensions [#remove-unnecessary-extensions-7] Video SDK provides optional extension dynamic libraries. The name of the extension is suffixed with `extension`. See the [extension list](#extension-list) for details on the function and size of the extensions. Refer to the following ways to exclude these extensions to reduce the size of the app. Open the `Assets/Agora-RTC-Plugin/Agora-Unity-RTC-SDK/Plugins` folder in Unity Editor. It contains dynamic libraries for iOS, macOS, Windows, and Android. As shown below: ![Reduce App Size](https://assets-docs.agora.io/images/video-sdk/unity-app-size-step1.png) * **Android**: If your target platform is Android, consider deleting the following files under the path `Android/AgoraRtcEngineKit.plugin/libs`: * `arm64-v8a/<*>_extension.so` * `armeabi-v7a/<*>_extension.so` * `x86/<*>_extension.so` * `x86_64/<*>_extension.so` Only delete these files if they are not required for your application to function correctly. * **iOS**: If your target platform is iOS, you can safely delete any unused `<*>Extension.framework` files located in the `iOS` folder of your project. * **macOS**: For macOS targets, you may delete any unused `<*>Extension.framework` files found in the `macOS/AgoraRtcWrapperUnity.bundle/Contents/Frameworks` path. * **Windows**: If targeting Windows, you have the option to delete `<*>extension.dll` or `<*>extension.dll.lib` files located in the `x86` or `x86_64` folder. Exercise caution when deleting files, and always make sure that any removals do not impact the functionality of your application. ### Delete files from the exported native project [#delete-files-from-the-exported-native-project] When exporting a native project from Unity for a target platform, the dynamic library corresponding to that platform is copied to the native project. To remove unnecessary files, delete the dynamic libraries ending with `extension` directly from the exported native project. ## Reference [#reference-8] This section contains content that completes the information in this page, or points you to documentation that explains other aspects to this product. ### Extension list [#extension-list-7] Refer to the following information for an introduction to each Video SDK extension and the increase in the size of your app after integration. The information in this section is based on version 4.4.0 of the Video SDK. **AI Noise Suppression** The Video SDK supports a new version of AI noise suppression, which provides better vocal fidelity, cleaner noise suppression, and adds de-reverberation capabilities.
