html5 – 如何在Web Audio Api中释放缓冲区？

以下代码模拟连续加载新缓冲区的回放.我需要web audio api来添加效果混音,所以每个人都可以通过他的表现听到实时结果

不幸的是,这段代码吞噬了整个ram并崩溃了移动和桌面游猎.我不知道如何在播放后释放那些大缓冲区,我不再需要它们.我真的需要在内存中加载新的大数据.有谁有想法？否则我会遇到前8个无法再加载的文件.

var context = new webkitAudioContext();
var @R_900_10586@l=0;

function onTouchStart(){
    seTinterval(function(){
    @R_900_10586@l+=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(@R_900_10586@l,'mb'); //
    },1000);
}

document.addEventListener( "touchstart",onTouchStart );
document.addEventListener( "click",onTouchStart );
