This is a react-native link module for audio recorder and player. This is not a playlist audio module and this library provides simple recorder and player functionalities for both android and ios platforms. This only supports default file extension for each platform. This module can also handle file from url.

• Version 3 Release Note

• Happy Blog.

• From version 3.0.+, a critical migration has been done. Current version is not much different from version 2.0.+ in usability, but there are many changes internally. Also note that it supports iOS platform version 10.0 or newer.

  1. Codebase has been re-written to kotlin for Android and swift for iOS. Please follow the post installation for this changes.

     [iOS]

     • AVAudioPlayer has been migrated to AVPlayer which supports stream and more possibilities #231, #245, #275.

  2. pauseRecorder and resumeRecorder features are added.

     • Caveat Android now requires minSdk of 24.

  3. Renamed callback variables.

     export type RecordBackType = {
       isRecording?: boolean;
       currentPosition: number;
       currentMetering?: number;
     };
     
     export type PlayBackType = {
       isMuted?: boolean;
       currentPosition: number;
       duration: number;
     };

  4. subscriptionDuration offset not defaults to 0.5 which is 500ms.

     • Resolve #273

• There has been vast improvements in #114 which is released in 2.3.0. We now support all RN versions without any version differenciating. See below installation guide for your understanding.

$ yarn add react-native-audio-recorder-player

[iOS only]

npx pod-install

$ react-native link react-native-audio-recorder-player

1. In XCode, in the project navigator, right click Libraries ➜ Add Files to [your project's name]
2. Go to node_modules ➜ react-native-audio-recorder-player and add RNAudioRecorderPlayer.xcodeproj
3. In XCode, in the project navigator, select your project. Add libRNAudioRecorderPlayer.a to your project's Build Phases ➜ Link Binary With Libraries
4. Run your project (Cmd+R)<

1. Open up android/app/src/main/java/[...]/MainApplication.java

• Add import package com.dooboolab.audiorecorderplayer.RNAudioRecorderPlayerPackage; to the imports at the top of the file
• Add new RNAudioRecorderPlayerPackage() to the list returned by the getPackages() method

2. Append the following lines to android/settings.gradle:

   include ':react-native-audio-recorder-player'
   project(':react-native-audio-recorder-player').projectDir = new File(rootProject.projectDir, 	'../node_modules/react-native-audio-recorder-player/android')
   

3. Insert the following lines inside the dependencies block in android/app/build.gradle:

     compile project(':react-native-audio-recorder-player')
   

On iOS you need to add a usage description to Info.plist:

<key>NSMicrophoneUsageDescription</key>
<string>Give $(PRODUCT_NAME) permission to use your microphone. Your record wont be shared without your permission.</string>

Also, add swift bridging header if you haven't created one for swift compatibility.

On Android you need to add a permission to AndroidManifest.xml:

<uses-permission android:name="android.permission.RECORD_AUDIO" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />

Also, android above Marshmallow needs runtime permission to record audio. Using react-native-permissions will help you out with this problem. Below is sample usage before when before staring the recording.

if (Platform.OS === 'android') {
  try {
    const grants = await PermissionsAndroid.requestMultiple([
      PermissionsAndroid.PERMISSIONS.WRITE_EXTERNAL_STORAGE,
      PermissionsAndroid.PERMISSIONS.READ_EXTERNAL_STORAGE,
      PermissionsAndroid.PERMISSIONS.RECORD_AUDIO,
    ]);

    console.log('write external stroage', grants);

    if (
      grants['android.permission.WRITE_EXTERNAL_STORAGE'] ===
        PermissionsAndroid.RESULTS.GRANTED &&
      grants['android.permission.READ_EXTERNAL_STORAGE'] ===
        PermissionsAndroid.RESULTS.GRANTED &&
      grants['android.permission.RECORD_AUDIO'] ===
        PermissionsAndroid.RESULTS.GRANTED
    ) {
      console.log('Permissions granted');
    } else {
      console.log('All required permissions not granted');
      return;
    }
  } catch (err) {
    console.warn(err);
    return;
  }
}

Lastly, you need to enable kotlin. Please change add the line below in android/build.gradle.

buildscript {
  ext {
      buildToolsVersion = "29.0.3"
+     // Note: Below change is necessary for pause / resume audio feature. Not for Kotlin.
+     minSdkVersion = 24
      compileSdkVersion = 29
      targetSdkVersion = 29
+     kotlinVersion = '1.6.10'

      ndkVersion = "20.1.5948944"
  }
  repositories {
      google()
      jcenter()
  }
  dependencies {
      classpath("com.android.tools.build:gradle:4.2.2")
+     classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlinVersion"
  }
...

All methods are implemented with promises.

interface AudioSet {
  AVSampleRateKeyIOS?: number;
  AVFormatIDKeyIOS?: AVEncodingType;
  AVModeIOS?: AVModeType;
  AVNumberOfChannelsKeyIOS?: number;
  AVEncoderAudioQualityKeyIOS?: AVEncoderAudioQualityIOSType;
  AudioSourceAndroid?: AudioSourceAndroidType;
  OutputFormatAndroid?: OutputFormatAndroidType;
  AudioEncoderAndroid?: AudioEncoderAndroidType;
}

More description on each parameter types are described in index.d.ts. Below is an example code.

const audioSet: AudioSet = {
  AudioEncoderAndroid: AudioEncoderAndroidType.AAC,
  AudioSourceAndroid: AudioSourceAndroidType.MIC,
  AVModeIOS: AVModeIOSOption.measurement,
  AVEncoderAudioQualityKeyIOS: AVEncoderAudioQualityIOSType.high,
  AVNumberOfChannelsKeyIOS: 2,
  AVFormatIDKeyIOS: AVEncodingOption.aac,
};
const meteringEnabled = false;

const uri = await this.audioRecorderPlayer.startRecorder(
  path,
  audioSet,
  meteringEnabled,
);

this.audioRecorderPlayer.addRecordBackListener((e: any) => {
  this.setState({
    recordSecs: e.currentPosition,
    recordTime: this.audioRecorderPlayer.mmssss(Math.floor(e.currentPosition)),
  });
});

• Default path for android uri is {cacheDir}/sound.mp4.
• Default path for ios uri is {cacheDir}/sound.m4a.

import AudioRecorderPlayer from 'react-native-audio-recorder-player';

const audioRecorderPlayer = new AudioRecorderPlayer();

onStartRecord = async () => {
  const result = await this.audioRecorderPlayer.startRecorder();
  this.audioRecorderPlayer.addRecordBackListener((e) => {
    this.setState({
      recordSecs: e.currentPosition,
      recordTime: this.audioRecorderPlayer.mmssss(
        Math.floor(e.currentPosition),
      ),
    });
    return;
  });
  console.log(result);
};

onStopRecord = async () => {
  const result = await this.audioRecorderPlayer.stopRecorder();
  this.audioRecorderPlayer.removeRecordBackListener();
  this.setState({
    recordSecs: 0,
  });
  console.log(result);
};

onStartPlay = async () => {
  console.log('onStartPlay');
  const msg = await this.audioRecorderPlayer.startPlayer();
  console.log(msg);
  this.audioRecorderPlayer.addPlayBackListener((e) => {
    this.setState({
      currentPositionSec: e.currentPosition,
      currentDurationSec: e.duration,
      playTime: this.audioRecorderPlayer.mmssss(Math.floor(e.currentPosition)),
      duration: this.audioRecorderPlayer.mmssss(Math.floor(e.duration)),
    });
    return;
  });
};

onPausePlay = async () => {
  await this.audioRecorderPlayer.pausePlayer();
};

onStopPlay = async () => {
  console.log('onStopPlay');
  this.audioRecorderPlayer.stopPlayer();
  this.audioRecorderPlayer.removePlayBackListener();
};

If you want to get actual uri from the record or play file to actually grab it and upload it to your bucket, just grab the resolved message when using startPlay or startRecord method like below.

To access the file with more reliability, please use rn-fetch-blob. For example, below.

const dirs = RNFetchBlob.fs.dirs;
const path = Platform.select({
  ios: 'hello.m4a',
  android: `${this.dirs.CacheDir}/hello.mp3`,
});

const uri = await audioRecorderPlayer.startRecord(path);

Also, above example helps you to setup manual path to record audio. Not giving path param will record in default path as mentioned above.

1. Goto Example folder by running cd Example.
2. Run yarn install && yarn start.
3. Run yarn ios to run on ios simulator and yarn android to run on your android device.
