如何使用從as3.0 aspx腳本aspx腳本轉換字節數組爲mp3？

Question

在Flash as3.0中錄製的語音存儲在BytesArray變量中。現在需要將記錄的聲音存儲爲aspx腳本中的.mp3或.wav文件。任何可以幫助我？如何將字節數組轉換爲音頻格式並保存在服務器中的任何概念請分享。

參考以下我的代碼。這段代碼是錄製你的聲音後轉換爲wav或mp3保存的技巧。轉換輸出mp3和wav文件是保證與C和Java的套接字通信。我測試了Windows-XP（32位）Windows7（64位），MacOSX，Android。

這裏使用的框架是鏈接。

WAVWriter： WAVWriter

ShineMP3Encoder： ShineMP3Encoder

import com.adobe.audio.format.WAVWriter; 
import fr.kikko.lab.ShineMP3Encoder; 
import flash.events.SampleDataEvent; 
import flash.media.Microphone; 
import flash.media.Sound; 
import flash.utils.ByteArray; 
import flash.events.Event; 

var mp3encoder:ShineMP3Encoder; 
var microphone:Microphone; 
var isRecording:Boolean=false; 
var soundRecording:ByteArray; 

function startMicRecording():void 
{ 
    isRecording=true; 
    soundRecording = new ByteArray(); 
    microphone=Microphone.getMicrophone(); 
    microphone.rate=44; 
    microphone.addEventListener(SampleDataEvent.SAMPLE_DATA, gotMicData); 
} 

function stopMicRecording():void { 

    isRecording=false; 
    microphone.removeEventListener(SampleDataEvent.SAMPLE_DATA, gotMicData); 
    soundRecording.position=0; 

    convert2MP3(); 
} 


function gotMicData(micData:SampleDataEvent):void 
{ 
    soundRecording.writeBytes(micData.data); 
} 

function convert2MP3():void 
{ 
    var wavWrite:WAVWriter = new WAVWriter(); 
    wavWrite.numOfChannels=1; 
    wavWrite.sampleBitRate=16; 
    wavWrite.samplingRate=44100; 

    var wav:ByteArray = new ByteArray(); 

    wavWrite.processSamples(wav, soundRecording, 44100,1); 
    wav.position=0; 

    /* 
    If the process is compressed into mp3 if you have big problems, 
    just as .wav format save. following code: 
    var file:FileReference = new FileReference(); 
    file.save(wav,"your_file_name.wav"); 
    */ 

    mp3encoder=new ShineMP3Encoder(wav); 
    mp3encoder.addEventListener(Event.COMPLETE, onEncoded); 
    mp3encoder.start(); 
} 

function onEncoded(e:Event):void 
{ 
    mp3encoder.mp3Data.position=0; 
    mp3encoder.saveAs("your_file_name.mp3"); 
} 

startMicRecording();
