1# Audio Interruption Mode Development 2 3## Introduction 4The audio interruption mode is used to control the playback of multiple audio streams. 5 6Audio applications can set the audio interruption mode to independent or shared under **AudioRenderer**. 7 8In shared mode, multiple audio streams share one session ID. In independent mode, each audio stream has an independent session ID. 9 10**Asynchronous operation**: To prevent the UI thread from being blocked, most **AudioRenderer** calls are asynchronous. Each API provides the callback and promise functions. The following examples use the promise functions. 11 12## How to Develop 13 14For details about the APIs, see [AudioRenderer in Audio Management](../reference/apis/js-apis-audio.md#audiorenderer8). 15 161. Use **createAudioRenderer()** to create an **AudioRenderer** instance. 17 18 Set parameters of the **AudioRenderer** instance in **audioRendererOptions**. 19 20 This instance is used to render audio, control and obtain the rendering status, and register a callback for notification. 21 22```js 23 import audio from '@ohos.multimedia.audio'; 24 25 var audioStreamInfo = { 26 samplingRate: audio.AudioSamplingRate.SAMPLE_RATE_44100, 27 channels: audio.AudioChannel.CHANNEL_1, 28 sampleFormat: audio.AudioSampleFormat.SAMPLE_FORMAT_S16LE, 29 encodingType: audio.AudioEncodingType.ENCODING_TYPE_RAW 30 } 31 32 var audioRendererInfo = { 33 content: audio.ContentType.CONTENT_TYPE_SPEECH, 34 usage: audio.StreamUsage.STREAM_USAGE_VOICE_COMMUNICATION, 35 rendererFlags: 1 36 } 37 38 var audioRendererOptions = { 39 streamInfo: audioStreamInfo, 40 rendererInfo: audioRendererInfo 41 } 42 43let audioRenderer = await audio.createAudioRenderer(audioRendererOptions); 44 ``` 45 462. Set the audio interruption mode. 47 48 After the **AudioRenderer** instance is initialized, you can set the audio interruption mode.<br> 49 50 ```js 51 var mode_ = audio.InterruptMode.SHARE_MODE; 52 await this.audioRenderer.setInterruptMode(mode_).then(() => { 53 console.log('[JSAR] [SetInterruptMode] Setting: '+ (mode_ == 0? " share mode":"independent mode") + "success"); 54 }); 55 ``` 56
