Large or small. oneshot sources are not releasing buffers and will eat whole ram.
unfortunately there is no way to do it manually like it is in webgl right now.
following sample crashes webkit both mobile and dektop.as result of memory depletion ?
current ipad2 mobile safari ios 6.0.1 crash after 8 oneshots played.
current chrome 24.0.1312.52m crash after  17 oneshots played.


var context = new webkitAudioContext();
var total=0;

function onTouchStart(){
    setInterval(function(){
    total+=10;
    var source = context.createBufferSource();    
    source.connect(context.destination);
    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.
    console.log(total,'mb'); 
    },1000);
}

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