# Audio Editor Kit Sample English | [中文](README_ZH.md) ## Table of Contents * [Introduction](#introduction) * [Project directory structure](#project-directory-structure) * [Running Procedure](#running-procedure) * [Supported environment](#supported-environment) * [License](#license) ## Introduction HUAWEI Audio Editor Kit provides a wide range of audio editing capabilities, including audio import/expert/editing/extracting and format conversion. You can easily integrate them into your app as needed through the kit's open, excellent, yet easy-to-use APIs. This sample code is used to describe how to use the Audio Editor Kit SDK. - Imports audio files in batches, and generates and previews the audio wave for a single audio or multiple audios. - Supports basic audio editing operations such as changing the volume, adjusting the tempo or pitch, and copying and deleting audio. - Adds one or more special effects to audio, including the music style, sound field, equalizer, fade-in/out, voice changer, sound effect, scene effect, and spatial audio - Supports audio recording and importing. - Separates audio sources for an audio file. - Reduces the quasi-steady-state noises and sudden loud noises in audio collected from two microphones, and repairs and enhances the human voice to improve the audio quality. - Extracts audio from video files in formats like MP4. - Converts audio format to MP3, WAV, or FLAC. - Supports AI dubbing: converts text into voice of different timbres. - Supports song synthesis: Generates beautiful songs based on the input lyrics (only in China). ## Project directory structure ``` |-- apk |-- app |-- com.huawei.hms.audioeditor.demo |-- MainActivity // Audio Editor UI SDK entry, format conversion entry, and audio extraction entry. |-- AudioFormatActivity // Demo Format Conversion. |-- AudioFilePickerActivity // Select the audio file and list for the demo. |-- FileApiActivity // Interfaces of Demo Function Files. |-- StreamApiActivity // Streaming Interfaces of Demo Functions. |-- AudioBaseActivity // Integration of basic demo functions. |-- AiDubbingAudioActivity // AI dubbing integration. |-- SongSynthesisActivity // Song synthesis function integration. |-- base_audioeditor |-- com.huawei.hms.audioeditor.demo |-- AudioBaseActivity // Integration of basic demo functions. |-- aidubbing_audioeditor |-- com.huawei.hms.audioeditor.demo |-- AiDubbingAudioActivity // AI dubbing functions. ``` ## Running Procedure - Clone the code base to the local host. - If you haven't already registered as a developer, register and create an app on [AppGalleryConnect](https://developer.huawei.com/consumer/cn/service/josp/agc/index.html). - Replacing the sample-agconnect-services.json File in the Project - Compile and run on an Android device. ## Supported Environment Android SDK 24 or later and JDK 1.8 or later are recommended. ## Question or issues If you want to evaluate more about HMS Core, [r/HMSCore on Reddit](https://www.reddit.com/r/HuaweiDevelopers/) is for you to keep up with latest news about HMS Core, and to exchange insights with other developers.
