Controlling interval between sound within a loop?

Hi,

would anyone have an idea how this could best be done?

I have a sound object which should loop continuously but the speed of looping should be dependant on the speed of a moving mc on stage.

I tried something like this:


Sound.prototype.playAtInterval = function(nMillis)
{
	var currentSound = this;
	var nInterval = nMillis + this.duration;
	var nCounter = 0;
	var startTime;
	var isInitialized = false;
	var soundTimer_mc = _root.createEmptyMovieClip("soundTimer_mc", 1);
	soundTimer_mc.onEnterFrame = function()
	{
		if (!isInitialized)
		{
			isInitialized = true;
			startTime = getTimer();
		}
		var currentTime = getTimer();
		var nDiff = currentTime - (startTime + (nCounter * nInterval));
		if (nDiff > nCounter * nInterval)
		{
			currentSound.start();
			nCounter++;
		}
	}
}
var mySound = new Sound();
mySound.attachSound("spinner_sound");
mySound.playAtInterval(10);

but when the interval is too small the sound doesn’t loop evenly, I guess because of the onEnterFrame.

Any other ideas?
