    Cordova provides a plugin to play sounds in your mobile application. It can record an audio file and also play back audio file on the device.

    Installing the plugin:
     

    cordova plugin add cordova-plugin-media

    It has a Media constructor. You can check by showing it on device ready.
     

    document.addEventListener("deviceready", onDeviceReady, false);
    function onDeviceReady() {
        console.log(Media);
    }
    var media = new Media(src, mediaSuccess, [mediaError], [mediaStatus]);

    where:
    src : It is a path for audio file.
    mediaSuccess : optional. It is a callback function that is executed when a media file completes its current action.
    mediaError : optional. It is executed when there is some error.
    mediaStatus : optional. It is executed when there is need to change status of audio file.

    mediaStatus constants:

    * Media.MEDIA_NONE = 0;
    * Media.MEDIA_STARTING = 1;
    * Media.MEDIA_RUNNING = 2;
    * Media.MEDIA_PAUSED = 3;
    * Media.MEDIA_STOPPED = 4;

    There are some methods which can be used for audio files:
    media.play: It is used to start audio file.
    media.pause: It is used to pause playback audio file.
    media.stop: It is used to stop audio file.
    media.setVolume: It is used to set the audio file volume.

    Example:

    // Play audio file
    function playAudio(url) {
        // Play the audio file at url
        var my_media = new Media(url,
            // success callback
            function() {
                console.log("playAudio():Audio Success");
            },
            // error callback
            function(err) {
                console.log("playAudio():Audio Error: "+err);
        });
    
        // Play audio
        my_media.play();
    
        // Mute volume after 2 seconds
        setTimeout(function() {
            my_media.setVolume('0.0');
        }, 2000);
    
        // Set volume to 1.0 after 5 seconds
        setTimeout(function() {
            my_media.setVolume('1.0');
        }, 5000);
    }
