Ti.AudioVisualizerView

This is the Titanium module for wrappng Visualizer class of Android. It uses https://github.com/felixpalmer/android-visualizer

An view like imageView that takes the input from the Android MediaPlayer and displays visualizations, like in iTunes or WinAmp.

or more complex:

Usage:

For usage in Marshmellow devices, you need AUDIO_RECORDING permission on runtime. You must wrap the call of Visualizer into a permissionRequester.

! function() {
    var Visualizer = require('ti.audiovisualizerview');
    var window = Ti.Ui.createWindow();
    window.addEventListener('open',function) {
        var visualizerView = Visualizer.createView({
            width : 500,
            audioSessionId :0,
            lifecycleContainer : window 
            height : 200
        });
        visualizerView.addEventListener('ready', function() {
            visualizerView.addLineRenderer();
            visualizerView.addBarGraphRenderer({
                color : '#326598',
                width : 32.0,
            });
        });
        window.add(visualizerView);
    });
    Ti.Media.createAudioPlayer({
        url : "http://audio.scdn.arkena.com/11016/fip-midfi128.mp3"
    }).start();
    window.open();
}();

The optional audioSessionId 0 means you want visualize the mixer out. In other cases you need the ID. The standard mediaPlayer doesn't gives you this ID. There is a JIRA ticket: https://jira.appcelerator.org/browse/AC-3538

YOu can use this code to retreive audioSessionId:

var mp = require('com.kcwdev.audio').createAudioPlayer({
    url : "https://raw.githubusercontent.com/felixpalmer/android-visualizer/master/res/raw/test.mp3"
});
mp.start();
console.log(mp.getAudioSessionId());
