如何使用ASPX脚本闪光灯AS3.0转换字节数组到MP3？ [英] How to convert byte array to mp3 using aspx script from flash as3.0?

问题描述

在闪存AS3.0记录的话音被存储在一个BytesArray变量。现在需要存储录制的声音作为mp3或者.wav文件的ASPX脚本。任何能帮助我吗？如何字节数组转换为音频格式并保存在服务器中的任何概念，欢迎交流。

In Flash as3.0 recorded voice is stored in a BytesArray variable. Now need to store the recorded sound as .mp3 or .wav file in aspx script. Any can help me? How to convert byte array to audio format and save in server any concept please share.

推荐答案

指一个关注我的code。这code是有关录制你的声音后转换为WAV或MP3救技能。转换输出MP3和WAV文件是保证有关使用C和Java的socket通信。我在Windows-XP测试（32位）的Windows7（64位），MacOSX上，Android系统。

refer a following my code. this code is skills about after recording your voice to be converted to wav or mp3 to save. converted output mp3 and wav file is is guaranteed about socket communication with the C and Java. I tested in Windows-xp(32bit) Windows7(64bit), MacOSX, Android.
