First install the npm package from your app directory:
npm install rn-sound --saveIn XCode, right click Libraries. Click Add Files to "[Your project]". Navigate to node_modules/rn-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).
Edit android/settings.gradle to declare the project directory:
include ':RNSound', ':app'
project(':RNSound').projectDir = new File(rootProject.projectDir, '../node_modules/rn-sound/android')
Edit android/app/build.gradle to declare the project dependency:
dependencies {
...
compile project(':RNSound')
}
Edit android/app/src/main/java/.../MainActivity.java to register the native module:
...
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
...
}Save your sound clip files under the directory android/app/src/main/res/raw.
// Import the rn-sound module
var Sound = require('rn-sound');
// Sound.enableInSilenceMode(true); // if need to enable playback in silence mode, currently for iOS only
// Load the sound file 'whoosh.mp3' from the app bundle
var whoosh = new Sound('whoosh.mp3', Sound.MAIN_BUNDLE, (error) => {
if (error) {
console.log('failed to load the sound', error);
} else { // loaded successfully
console.log('duration in seconds: ' + whoosh.duration +
'number of channels: ' + whoosh.numberOfChannels);
}
});
// 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();
// Release the audio player resource
whoosh.release();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} Options object with the following options-
{
artist:"Some Artist", // Shows artist title in iOS Control Center
title:"Some track title" // Show Track title in iOS Control Center
}
Return true if the sound has been loaded.
onEnd {?function(successfully)} Optional callback function that gets called when the playback finishes successfully or an audio decoding error interrupts it.
Pause the sound.
Stop the playback.
Release the audio player resource associated with the instance.
Return the duration in seconds, or -1 before the sound gets loaded.
Return the number of channels (1 for mono and 2 for stereo sound), or -1 before the sound gets loaded.
Return the volume of the audio player (not the system-wide volume), ranging from 0.0 (silence) through 1.0 (full volume, the default).
value {number} Set the volume, ranging from 0.0 (silence) through 1.0 (full volume).
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).
value {number} Set the pan, ranging from -1.0 (full left) through 1.0 (full right).
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.
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).
callback {function(seconds, isPlaying)} Callback will receive the current playback position in seconds and whether the sound is being played.
value {number} Seek to a particular playback point in seconds.
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
value {function} Set a callback to be called when your audio is paused via Remote. e.g The user paused their Airplay Speaker or paused the sound from the Control Center. This will only be called if setCategory(value) is set to Playback
value {function} Set a callback to be called when your audio is played via Remote. e.g The user paused their Airplay Speaker or paused the sound from the Control Center. This will only be called if setCategory(value) is set to Playback
- To minimize playback delay, you may want to preload a sound file without calling
play()(e.g.var s = new Sound(...);) during app initialization. - You can play multiple sound files at the same time. Under the hood, this module uses
AVAudioSessionCategoryAmbientto mix sounds on iOS. - You may reuse a
Soundinstance for multiple playbacks. - On iOS, the module wraps
AVAudioPlayerwhich supports aac, aiff, mp3, wav etc. The full list of supported formats can be found at https://developer.apple.com/library/ios/documentation/AudioVideo/Conceptual/MultimediaPG/UsingAudio/UsingAudio.html - On Android, the module wraps
android.media.MediaPlayer. The full list of supported formats can be found at http://developer.android.com/guide/appendix/media-formats.html - You may chain non-getter calls, for example,
sound.setVolume(.5).setPan(.5).play().
