recOpen:function(){
            var This=this;
            var rec=this.rec=Recorder({
                type:This.type
                ,bitRate:This.bitRate
                ,sampleRate:This.sampleRate
                ,onProcess:function(buffers,powerLevel,duration,sampleRate){
                    This.duration=duration;
                    This.powerLevel=powerLevel;

                    This.wave.input(buffers[buffers.length-1],powerLevel,sampleRate);
                }
            });

            This.dialogInt=setTimeout(function(){//定时8秒后打开弹窗，用于监测浏览器没有发起权限请求的情况
