📦 Installation

npm

npm install react-native-sound

yarn

yarn add react-native-sound

🏗️ New Architecture Support

This library supports both the old and new React Native architecture:

✅ Old Architecture: Uses traditional NativeModules
✅ New Architecture: Uses TurboModules for better performance
✅ Expo: Compatible with custom development builds (not Expo Go)

🛠️ Troubleshooting

Common Issues

`undefined is not an object (evaluating 'RNSound.IsAndroid')`

This usually indicates a linking issue. Try:

Clear build cache:
```
cd android && ./gradlew cleanBuildCache
```
Reset Metro cache:
```
npx react-native start --reset-cache
```

Clean and rebuild:

# iOS
cd ios && rm -rf build && cd .. && npx react-native run-ios

# Android
cd android && ./gradlew clean && cd .. && npx react-native run-android

iOS Build Issues

Ensure audio files are added to Xcode project bundle
Check that AVFoundation framework is linked (automatically handled by CocoaPods)

Android Build Issues

Place audio files in android/app/src/main/res/raw/
Use lowercase filenames without spaces or special characters
Clear build cache if encountering linking issues

🚀 Quick Start

Setup Audio Files

Android

Save audio files in android/app/src/main/res/raw/:

android/app/src/main/res/raw/
├── whoosh.mp3        ✅ Correct
├── button_click.wav  ✅ Correct
└── my-sound.mp3      ❌ Use underscores: my_sound.mp3

Note: Use lowercase, underscored filenames. No subdirectories allowed.

iOS

Open your project in Xcode
Right-click your project → "Add Files to [PROJECT]"
Select your audio files and ensure they're added to the app target

Basic Usage

import Sound from "react-native-sound";

// Enable playback in silence mode (important for iOS)
Sound.setCategory("Playback");

// Load a sound file from the app bundle
const whoosh = new Sound("whoosh.mp3", Sound.MAIN_BUNDLE, (error) => {
  if (error) {
    console.log("Failed to load the sound", error);
    return;
  }

  // Sound loaded successfully
  console.log("Duration:", whoosh.getDuration(), "seconds");
  console.log("Channels:", whoosh.getNumberOfChannels());

  // Play the sound
  whoosh.play((success) => {
    if (success) {
      console.log("Successfully finished playing");
    } else {
      console.log("Playback failed due to audio decoding errors");
    }
  });
});

// Audio controls
whoosh.setVolume(0.5); // 50% volume
whoosh.setPan(1); // Full right stereo
whoosh.setNumberOfLoops(-1); // Loop indefinitely

// Get current properties
console.log("Volume:", whoosh.getVolume());
console.log("Pan:", whoosh.getPan());
console.log("Loops:", whoosh.getNumberOfLoops());

// Seek to specific time
whoosh.setCurrentTime(2.5);

// Get current playback position
whoosh.getCurrentTime((seconds) => {
  console.log("Current time:", seconds);
});

// Control playback
whoosh.pause(); // Pause playback
whoosh.stop(() => {
  // Stop and rewind
  whoosh.play(); // Play from beginning
});

// Always release resources when done
whoosh.release();

Advanced Examples

Loading from Different Sources

// From app bundle (most common)
const bundleSound = new Sound("sound.mp3", Sound.MAIN_BUNDLE, callback);

// From documents directory
const docSound = new Sound("sound.mp3", Sound.DOCUMENT, callback);

// From library directory
const libSound = new Sound("sound.mp3", Sound.LIBRARY, callback);

// From absolute path
const pathSound = new Sound("/path/to/sound.mp3", "", callback);

// From remote URL (iOS/Android only)
const urlSound = new Sound("https://example.com/sound.mp3", "", callback);

React Hook Example

import { useEffect, useRef, useState } from "react";
import Sound from "react-native-sound";

const useSound = (filename: string) => {
  const sound = useRef<Sound | null>(null);
  const [isLoaded, setIsLoaded] = useState(false);
  const [isPlaying, setIsPlaying] = useState(false);

  useEffect(() => {
    sound.current = new Sound(filename, Sound.MAIN_BUNDLE, (error) => {
      if (error) {
        console.log("Error loading sound:", error);
        return;
      }
      setIsLoaded(true);
    });

    return () => {
      sound.current?.release();
    };
  }, [filename]);

  const play = () => {
    if (sound.current && isLoaded) {
      sound.current.play((success) => {
        setIsPlaying(false);
      });
      setIsPlaying(true);
    }
  };

  const stop = () => {
    if (sound.current) {
      sound.current.stop();
      setIsPlaying(false);
    }
  };

  return { play, stop, isLoaded, isPlaying };
};

📝 Important Notes

Performance Tips

Preload sounds during app initialization to minimize playback delay
Reuse Sound instances for multiple playbacks of the same file
Avoid race conditions by ensuring sounds are loaded before calling play()

Audio Session Behavior

iOS: Uses AVAudioSessionCategoryAmbient to mix multiple sounds
Multiple playback: You can play several sound files simultaneously
Background audio: Configure audio categories for background playback

File Format Support

iOS (AVAudioPlayer)

Supports: AAC, AIFF, CAF, MP3, WAV, and more

📚 Complete format list

Android (MediaPlayer)

Supports: 3GPP, MP4, MP3, AAC, OGG, FLAC, WAV, and more

📚 Complete format list

Path Handling

Android absolute paths: Use /sdcard/ prefix (e.g., /sdcard/Downloads/sound.mp3)
Method chaining: Supported for setters (e.g., sound.setVolume(0.5).setPan(0.5).play())

Code Style

Follow existing TypeScript/JavaScript patterns
Use meaningful commit messages
Keep changes focused and atomic
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
On Android, the absolute path can start with '/sdcard/'. So, if you want to access a sound called "my_sound.mp3" on Downloads folder, the absolute path will be: '/sdcard/Downloads/my_sound.mp3'.
You may chain non-getter calls, for example, sound.setVolume(.5).setPan(.5).play().
