# Android音频捕获（录音） #

Android有一个内置的麦克风，通过它可以捕获音频和存储，或在手机进行播放。有很多方法可以做到这一点，但最常见的方法是通过MediaRecorder类。

Android提供MediaRecorder类录制音频或视频。为了使用MediaRecorder类，首先创建MediaRecorder类的一个实例。其语法如下给出。

MediaRecorder myAudioRecorder = new MediaRecorder();

现在设置源，输出编码格式和输出文件。下面的语法给出。

myAudioRecorder.setAudioSource(MediaRecorder.AudioSource.MIC);
    myAudioRecorder.setOutputFormat(MediaRecorder.OutputFormat.THREE_GPP);
    myAudioRecorder.setAudioEncoder(MediaRecorder.OutputFormat.AMR_NB);
    myAudioRecorder.setOutputFile(outputFile);

指定音频源和格式以及它的输出文件之后，我们就可以调用两种基本方法制备，开始记录音频。

myAudioRecorder.prepare();
    myAudioRecorder.start();

除了这些方法，还有其他的MediaRecorder类可以更好地控制音频和视频录制列出的方法。

这个例子提供了MediaRecorder类捕获音频的示范，MediaPlayer类来播放录制的音频。

为了试验这个例子，需要在实际设备上运行此例子。

让我们试着运行AndroidCapture应用程序。启动应用程序之前显示如下窗口，选择要运行的Android应用程序的选项。

![Anroid Capture Tutorial][]

选择移动设备作为一个选项，检看移动设备将显示如下界面：
