    <p>Hi guys I love Web Audio Api. The possibilities are fantastic. That being said its still in early stages. An what worries me most is that I have no idea how to release buffers / sounds that i no longer need. sound buffers with always new sontent since I will be mixing live sound from musicians / DJs / moderators connected via websockets</p> <p>the following code simulates load an playback of new buffers in a row. I need web audio api to add effects mixing and so everybody can hear live result with his performance</p> <p>Unfortunately this code eats whole ram and crashes both mobile and desktop safari. I have no idea how to release those large buffers once they vere played and I no longer need them .I really need to load new large data in their place in memory. Have anyone idea? Otherwise I am stuck with first 8 files played not able to load any more. </p> <pre><code>var context = new webkitAudioContext(); var total=0; function onTouchStart(){ setInterval(function(){ total+=10; source = context.createBufferSource(); source.connect(context.destination); // simulates loading large file source.buffer=context.createBuffer(1, 10*1024*1024, context.sampleRate); source.noteOn(0); source.noteOff(0); // acording to w3c spec resources should be deleted immediately. // making source property and call delete or =null will release nether source or buffer i am desperate. console.log(total,'mb'); // },1000); } document.addEventListener( "touchstart", onTouchStart ); document.addEventListener( "click", onTouchStart ); </code></pre>
