  1. I'm currently working on a jukebox in phaser but i found a big problem, when change more than 17 song mobile devices crushes. I start looking the memory usage on chrome and see that although i use audio destroy, clear game cache, and reset references memory usage keep rise song by song loaded. I could not find a solution in phaser so do the same example with howler, and it happened the same, the use of memory kept going up. Search the forums and find this interesting solution / advice that incredibly worked Is it possible to use the html5 tag in one audio and the webaudio Api in another on phaser? or fix the high memory usage? With this solution in my example i pass from 400mb on memory to 80mb on memory. The code: phaser-howler: var game = new Phaser.Game(800, 600, Phaser.CANVAS, 'phaser-example', { preload: preload, create: create ,update: update}); function preload() { game.load.spritesheet('button', 'assets/flixel-button.png', 80, 20); game.load.bitmapFont('nokia', 'assets/nokia16black.png', 'assets/nokia16black.xml'); game.load.json('audios', 'assets/audios.json', false); } var currentSong; var songList; var prevSong; var nextSong; var currIndex = -1; var logYPosition = 0; var logYSeparation = 2; var fontSize = 16; var currentTextLog; var timer = 0; var initTimer = 0; var downloadTime = 0; var decodingTime = 0; var songLength = 0;

ended = true; return; } logYPosition += fontSize + logYSeparation; var audios = _getAudioFilesArray(audioFolder,songList[currIndex],tempjs.audiotypes); initTimer = game.time.time; currentSong = new Howl({ src: audios, html5: true });
