解决方案
您需要存储的交给你的 gotMicData 到，然后保存的ByteArray 。要保存的事件名称，它是一个字符串（10个字符）。
一旦你这样做，你需要将文件和手工采样数据加载声音。你玩的声音后面的8倍......因为你在11千赫采样，但在播放声音在44千赫（4x写入）和声音是立体声，但麦克风是单声道（2X再次）。
您无法将数据保存为WAV文件直接...你记录的原始数据。如果你想通过写一个适当的WAV头的麻烦，那么你就不必打的移交样本数据的游戏和手中的文件，在声音对象。这是行使这个问题的范围之外。
祝你好运！

In the following code i am trying to save the microphone contents to a file.The saved file doesn't play and Every time the file is saved i see that the size is only of 10 bytes only.What am i doing wrong in the code.Can someone please show me the correct code to save it .And the saved file should play the recorded contents accordingly.

解决方案
You need to store the data that is handed to you in gotMicData into a ByteArray and then save that ByteArray. You are saving the event name, which is a string (10 characters long).
Once you do that, you need to load the file and hand sample data to the sound. You play the sound back 8 times... because you sampled at 11 KHz but the sound plays back at 44 KHz (4x writing) and the sound is Stereo but the mic is mono (2x again).
You can't save the data as a WAV file directly... you recorded raw data. If you want to go through the trouble of writing a proper WAV header, then you don't have to play the games of handing sample data and hand the file to the Sound object. That is an exercise outside of the scope of this question.
Good luck!
