标题: AS3与本地文件交互之——录音回放保存
系统要求：flash CS5以上（保证flashplayer播放器10.2以上），需要几个第三方的类，org.as3wavsound.WavSound，org.bytearray.micrecorder.MicRecorder，org.bytearray.micrecorder.encoder.WaveEncoder， org.bytearray.micrecorder.events.RecordingEvent，附件里面有。
打开flash CS5，新建AS3文档，舞台上放置四个按钮：btn1、btn2、btn3、btn4，两个动态文本框：txtMsg、displayMsg，
第一帧写代码：

1. import flash.display.StageAlign;
   
2. import flash.display.StageScaleMode;
   
3. import flash.events.Event;
   
4. import flash.events.MouseEvent;
   
5. import flash.media.Microphone;
   
6. 
   
7. import org.as3wavsound.WavSound;
   
8. import org.bytearray.micrecorder.MicRecorder;
   
9. import org.bytearray.micrecorder.encoder.WaveEncoder;
   
10. import org.bytearray.micrecorder.events.RecordingEvent;
    
11. 
    
12. stage.align = StageAlign.TOP_LEFT;
    
13. stage.scaleMode = StageScaleMode.NO_SCALE;
    
14. 
    
15. var recorder:MicRecorder = new MicRecorder( new WaveEncoder() );
    
16. var player:WavSound;
    
17. var _file:FileReference = new FileReference();
    
18. 
    
19. recorder.addEventListener(RecordingEvent.RECORDING, onRecording);
    
20. recorder.addEventListener(Event.COMPLETE, onRecordComplete);
    
21. 
    
22. btn2.visible = false;
    
23. btn3.visible = false;
    
24. btn4.visible = false;
    
25. 
    
26. btn1.addEventListener(MouseEvent.CLICK, startRecord);
    
27. btn2.addEventListener(MouseEvent.CLICK, stopRecord);
    
28. btn3.addEventListener(MouseEvent.CLICK, playBack);
    
29. btn4.addEventListener(MouseEvent.CLICK, saveFile);
    
30. 
    
31. function startRecord(event:MouseEvent):void
    
32. {
    
33. txtMsg.text = "正在录音";
    
34. recorder.record();
    
35. btn1.visible = false;
    
36. btn2.visible = true;
    
37. btn3.visible = false;
    
38. }
    
39. function stopRecord(event:MouseEvent):void
    
40. {
    
41. txtMsg.text = "录制完成,可以播放";
    
42. recorder.stop();
    
43. btn1.visible = true;
    
44. btn2.visible = false;
    
45. btn3.visible = true;
    
46. btn4.visible = true;
    
47. }
    
48. function playBack(event:MouseEvent):void
    
49. {
    
50. txtMsg.text = "正在播放";
    
51. player = new WavSound(recorder.output);
    
52. player.play();
    
53. 
    
54. btn1.visible = true;
    
55. btn2.visible = true;
    
56. btn3.visible = true;
    
57. }
    
58. function saveFile(event:MouseEvent):void
    
59. {
    
60. _file.save( recorder.output, "recorded.wav" );
    
61. }
    
62. 
    
63. function onRecording(event:RecordingEvent):void
    
64. {
    
65. displayMsg.text = "Recording since : " + event.time + " ms.";
    
66. }
    
67. function onRecordComplete(event:Event):void
    
68. {
    
69. //
    
70. }
