My playback method for voxel-recorder kinda sucks, and doesn't handle looping. Any better ideas than this?

Voxel-playback

for(var i=0; i<recording.length; i++){
  	var time = Math.ceil((recording[frame+i]['time']-recording[frame]['time'])/speed)
		setTimeout(function(){
			frame++
			assumeFrame(frame)
			if(frame===recording.length-1){
				if(loop){
					frame=0
					i=1
				}else{
					isPlaying=false
				}
			}
		}, time)
	}
