Installation

First install the npm package from your app directory:

npm install react-native-sound --save

Then link it automatically using:

react-native link react-native-sound

Manual Installation on iOS

This is not necessary if you have used react-native link

In XCode, right click Libraries. Click Add Files to "[Your project]". Navigate to node_modules/react-native-sound. Add the file RNSound.xcodeproj.

In the Project Navigator, select your project. Click the build target. Click Build Phases. Expand Link Binary With Libraries. Click the plus button and add libRNSound.a under Workspace.

Drag and drop sound files into Project Navigator to add them to the project. Verify that the files are packaged in the app bundle in either way:

Select a sound file in the Project Navigator, tick the checkbox in the Target Membership list on the right.
Alternatively, click the build target, click Build Phases, expand Copy Bundle Resources, add the file if it's not already listed.

Run your project (⌘+R).

Manual Installation on Android

This is not necessary if you have used react-native link

Edit android/settings.gradle to declare the project directory:

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

Edit android/app/build.gradle to declare the project dependency:

dependencies {
  ...
  compile project(':react-native-sound')
}

Edit android/app/src/main/java/.../MainApplication.java to register the native module:

...
import com.zmxv.RNSound.RNSoundPackage; // <-- New
...

public class MainApplication extends Application implements ReactApplication {
  ...
  @Override
  protected List<ReactPackage> getPackages() {
    return Arrays.<ReactPackage>asList(
        new MainReactPackage(),
        new RNSoundPackage() // <-- New
    );
  }

For older versions of React Native you need to edit MainActivity.java instead:

...
import com.zmxv.RNSound.RNSoundPackage; // <-- New
...

public class MainActivity extends Activity implements DefaultHardwareBackBtnHandler {
  ...
    @Override
  protected void onCreate(Bundle savedInstanceState){
    ...
    mReactInstanceManager = ReactInstanceManager.builder()
      .setApplication(getApplication())
      ...
      .addPackage(new MainReactPackage())
      .addPackage(new RNSoundPackage()) // <-- New
      ...
  }

Basic usage

First you'll need to add audio files to your project.

Android: Save your sound clip files under the directory android/app/src/main/res/raw. Note that files in this directory must be lowercase and underscored (e.g. my_file_name.mp3) and that subdirectories are not supported by Android.
iOS: Open Xcode and add your sound files to the project (Right-click the project and select Add Files to [PROJECTNAME])

// Import the react-native-sound module
var Sound = require('react-native-sound');

// Enable playback in silence mode (iOS only)
Sound.setCategory('Playback');

// Load the sound file 'whoosh.mp3' from the app bundle
// See notes below about preloading sounds within initialization code below.
var whoosh = new Sound('whoosh.mp3', Sound.MAIN_BUNDLE, (error) => {
  if (error) {
    console.log('failed to load the sound', error);
    return;
  } 
  // loaded successfully
  console.log('duration in seconds: ' + whoosh.getDuration() + 'number of channels: ' + whoosh.getNumberOfChannels());
});

// Play the sound with an onEnd callback
whoosh.play((success) => {
  if (success) {
    console.log('successfully finished playing');
  } else {
    console.log('playback failed due to audio decoding errors');
  }
});

// Reduce the volume by half
whoosh.setVolume(0.5);

// Position the sound to the full right in a stereo field
whoosh.setPan(1);

// Loop indefinitely until stop() is called
whoosh.setNumberOfLoops(-1);

// Get properties of the player instance
console.log('volume: ' + whoosh.getVolume());
console.log('pan: ' + whoosh.getPan());
console.log('loops: ' + whoosh.getNumberOfLoops());

// Seek to a specific point in seconds
whoosh.setCurrentTime(2.5);

// Get the current playback point in seconds
whoosh.getCurrentTime((seconds) => console.log('at ' + seconds));

// Pause the sound
whoosh.pause();

// Stop the sound and rewind to the beginning
whoosh.stop(() => {
  // Note: If you want to play a sound after stopping and rewinding it,
  // it is important to call play() in a callback.
  whoosh.play();
});

// Release the audio player resource
whoosh.release();

API

`constructor(filename, basePath, onError, options)`

filename {string} Either absolute or relative path to the sound file

basePath {?string} Optional base path of the file. Omit this or pass '' if filename is an absolute path. Otherwise, you may use one of the predefined directories: Sound.MAIN_BUNDLE, Sound.DOCUMENT, Sound.LIBRARY, Sound.CACHES.

onError {?function(error, props)} Optional callback function. If the file is successfully loaded, the first parameter error is null, and props contains an object with two properties: duration (in seconds) and numberOfChannels (1 for mono and 2 for stereo sound), both of which can also be accessed from the Sound instance object. If an initialization error is encountered (e.g. file not found), error will be an object containing code, description, and the stack trace.

options {?object} Platform-specific options:

Windows Only: enableSMTCIntegration {?boolean}. Optional setting for windows to enable or disable SMTC integration (controlling your apps sounds or music via the keyboard, and the built-in media controls on Windows.) This is enabled by default. Set this to false when you don't want users to be able to control your sounds (e.g. sound effects.) See the Windows.Media.SystemMediaTransportControls documentation for more information.

`isLoaded()`

Return true if the sound has been loaded.

`play(onEnd)`

onEnd {?function(successfully)} Optional callback function that gets called when the playback finishes successfully or an audio decoding error interrupts it.

`pause(callback)`

callback {?function()} Optional callback function that gets called when the sound has been paused.

Pause the sound.

`stop(callback)`

callback {?function()} Optional callback function that gets called when the sound has been stopped.

Stop playback and set the seek position to 0.

`release()`

Release the audio player resource associated with the instance.

`getDuration()`

Return the duration in seconds, or -1 before the sound gets loaded.

`getNumberOfChannels()`

Return the number of channels (1 for mono and 2 for stereo sound), or -1 before the sound gets loaded.

`getVolume()`

Return the volume of the audio player (not the system-wide volume), ranging from 0.0 (silence) through 1.0 (full volume, the default).

`setVolume(value)`

value {number} Set the volume, ranging from 0.0 (silence) through 1.0 (full volume).

`getPan()`

Return the stereo pan position of the audio player (not the system-wide pan), ranging from -1.0 (full left) through 1.0 (full right). The default value is 0.0 (center).

`setPan(value)`

value {number} Set the pan, ranging from -1.0 (full left) through 1.0 (full right).

`getNumberOfLoops()`

Return the loop count of the audio player. The default is 0 which means to play the sound once. A positive number specifies the number of times to return to the start and play again. A negative number indicates an indefinite loop.

`setNumberOfLoops(value)`

value {number} Set the loop count. 0 means to play the sound once. A positive number specifies the number of times to return to the start and play again (iOS only). A negative number indicates an indefinite loop (iOS and Android).

`getCurrentTime(callback)`

callback {function(seconds, isPlaying)} Callback will receive the current playback position in seconds and whether the sound is being played.

`setCurrentTime(value)`

value {number} Seek to a particular playback point in seconds.

`setSpeed(value)`

value {number} Speed of the audio playback (iOS Only).

`setSpeakerphoneOn(value)`

speaker {boolean} Sets the speakerphone on or off (Android only).

It requires this permission in your AndroidManifest: <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS"/>

`enableInSilenceMode(enabled)` (deprecated)

enabled {boolean} Whether to enable playback in silence mode (iOS only).

Use the static method Sound.setCategory('Playback') instead which has the same effect.

`setCategory(value)` (deprecated)

Deprecated. Use the static method Sound.setCategory instead.

Static Methods

`Sound.setCategory(value, mixWithOthers) (iOS only)`

value {string} Sets AVAudioSession category, which allows playing sound in background, stop sound playback when phone is locked, etc. Parameter options: "Ambient", "SoloAmbient", "Playback", "Record", "PlayAndRecord", "AudioProcessing", "MultiRoute".

More info about each category can be found in https://developer.apple.com/library/ios/documentation/AVFoundation/Reference/AVAudioSession_ClassReference/#//apple_ref/doc/constant_group/Audio_Session_Categories

mixWithOthers {boolean} can be set to true to force mixing with other audio sessions.

To play sound in the background, make sure to add the following to the Info.plist file.

<key>UIBackgroundModes</key>
<array>
  <string>audio</string>
</array>

Notes

To minimize playback delay, you may want to preload a sound file without calling play() (e.g. var s = new Sound(...);) during app initialization. This also helps avoid a race condition where play() may be called before loading of the sound is complete, which results in no sound but no error because loading is still being processed.
You can play multiple sound files at the same time. Under the hood, this module uses AVAudioSessionCategoryAmbient to mix sounds on iOS.
You may reuse a Sound instance for multiple playbacks.
On iOS, the module wraps AVAudioPlayer that supports aac, aiff, mp3, wav etc. The full list of supported formats can be found at https://developer.apple.com/library/content/documentation/MusicAudio/Conceptual/CoreAudioOverview/SupportedAudioFormatsMacOSX/SupportedAudioFormatsMacOSX.html
On Android, the module wraps android.media.MediaPlayer. The full list of supported formats can be found at https://developer.android.com/guide/topics/media/media-formats.html
You may chain non-getter calls, for example, sound.setVolume(.5).setPan(.5).play().
