 效果演示

可以实现录音,回放,还可以把录音保存到本地(wav文件)
主要代码
import flash.display.Sprite;
import flash.display.StageAlign;
import flash.display.StageScaleMode;

var recorder:MicRecorder = new MicRecorder( new WaveEncoder() );
var player:WavSound;
var _file:FileReference = new FileReference();

stage.align = StageAlign.TOP_LEFT;
stage.scaleMode = StageScaleMode.NO_SCALE;

recorder.addEventListener(RecordingEvent.RECORDING, onRecording);
recorder.addEventListener(Event.COMPLETE, onRecordComplete);

bt2.visible = false;
bt3.visible = false;
bt4.visible = false;

bt1.addEventListener(MouseEvent.CLICK, bt1_ck);

function bt1_ck(event:MouseEvent):void
{
 txtMsg.text = "正在录音";
 recorder.record();
 bt1.visible = false;
 bt2.visible = true;
 bt3.visible = false;
}

bt2.addEventListener(MouseEvent.CLICK, bt2_ck);

function bt2_ck(event:MouseEvent):void

 //recorder.record();
 recorder.stop();

}

bt3.addEventListener(MouseEvent.CLICK, bt3_ck);

}

bt4.addEventListener(MouseEvent.CLICK,bt4_ck);

function bt4_ck(event:MouseEvent):void

}

function onRecording(event:RecordingEvent):void
