Simplest Sound Recorder for React Native

react-native-sound-recorder

No-hassle Sound Recorder for React Native.

There are existing libraries out in the wild

• https://github.com/MisterAlex95/react-native-record-sound
• https://github.com/jsierles/react-native-audio

Why reinvent the wheel?

At the time of writing, the above libaries are either inconsistent or incomplete.

For example, the same startRecording call returns a Promise on Android but null in iOS.

Or stopRecording doesn't give a promise/callback at all. So forcing user to do silly things like "wait for 1 second" in order to make sure file is well written to disk.

Getting started

$ npm install react-native-sound-recorder --save

or

$ yarn add react-native-sound-recorder

if RN >= 0.60.0

Autolink should work

if RN < 0.60.0

Mostly automatic installation

$ react-native link react-native-sound-recorder

Manual installation

iOS

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

Android

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

• Add import com.kevinresol.react_native_sound_recorder.RNSoundRecorderPackage; to the imports at the top of the file
• Add new RNSoundRecorderPackage() to the list returned by the getPackages() method

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

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

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

     compile project(':react-native-sound-recorder')
   

Permissions

iOS: Add the following entry to Info.plist:

<key>NSMicrophoneUsageDescription</key>
<string>This sample uses the microphone to record your speech and convert it to text.</string>

Android: Add the following entry to AndroidManifest.xml:

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

Usage

import SoundRecorder from 'react-native-sound-recorder';

// Note: You may need to request runtime permission(s) first.

SoundRecorder.start(SoundRecorder.PATH_CACHE + '/test.mp4')
	.then(function() {
		console.log('started recording');
	});

SoundRecorder.stop()
	.then(function(result) {
		console.log('stopped recording, audio file saved at: ' + result.path);
	});
	
// Usage with Options:


 SoundRecorder.start(
        SoundRecorder.PATH_CACHE + '/' + fileName + '.mp4',
        {
          quality: SoundRecorder.QUALITY_MAX,
          format : SoundRecorder.FORMAT_AAC_ADTS,

        }
      ).then(function () {
       
 
      });
