Why another music module?

After trying to team up modules like react-native-sound, react-native-music-controls and react-native-google-cast, I've noticed that their structure and the way should be tied together can cause a lot problems (mainly on Android). Those can heavily affect the app stability and user experience.

All audio modules (like react-native-sound) don't play in a separated service on Android, which should only be used for simple audio tracks in foreground (such as sound effects, voice messages, etc)

react-native-music-controls is meant for apps using those audio modules, although it has a few problems due to how the audio is not directly tied to the controls, it can be pretty useful for casting (such as Chromecast)

react-native-google-cast works pretty well and also supports custom receivers, but it has fewer player controls, it's harder to integrate and still uses the Cast SDK v2

First Steps

If you want to get started with this module, check the Getting Started page. If you want detailed information about the API, check the Documentation. You can also look at our example project here.

Example

A basic example of how to play a track:

import VoiceProcessing from 'react-native-voice-processing';

const start = async () => {
    // Set up the player
    await VoiceProcessing.setupPlayer();

    // Add a track to the queue
    await VoiceProcessing.add({
        id: 'trackId',
        url: require('track.mp3'),
        title: 'Track Title',
        artist: 'Track Artist',
        artwork: require('track.png')
    });

    // Start playing it
    await VoiceProcessing.play();
};
start();

Roadmap (What to do in next)

get current amplitude DB or raw buffer.
Use in combination with Casting (WIP)/Google cast to seamlessly switch to anycast compatible device that supports custom media receivers.
this voice processor makes your voice sound like a robot, an alien, a baby, and many more. Put yourself in a pipe, in a bathroom, a hall, or a station. Speed your voice up, slow it down or alter its pitch.
