<P>
本文是作者毕设所设计到的技术,因为已经做完,所以想将一些技术总结与大家分享一下,希望能和大家有交流的机会.</P>
<P> </P>
<P> 捕获音频设备的核心代码先写如下:</P>
<P>AudioFormat audioFormat ; </P>
<P>Vector audioDeviceList ;</P>
<P> CpatureDeviceInfo cdi = null;</P>
<P> MediaLocator mediaLocator ; </P>
<P>MediaPlayer player ; </P>
<P>audioFormat = new AudioFormat(AudioFormat.LINEAR); </P>
<P>audioDeviceList = CpatureDeviceManager.getDeviceList(audioFormat); i</P>
<P>f(audioDeviceList == null || audioDeviceList.size() < 1 ) { </P>
<P> System.out.println("未捕获到音频设备,请检查设备是否正确连接"); } </P>
<P>else { </P>
<P> cdi = (CaptureDeviceInof)audioDeviceList.elementAt(0);
</P>
<P> mediaLocator = cdi.getLocator(); player = new
MediaPlayer();</P>
<P> player.setMediaLocator(mediaLocator);</P>
<P> player.addControllerListener(this); </P>
<P> player.realize(); } </P>
<P> public void controllerUpdate(ControllerEvent e) { </P>
<P> if(e instanceof RealizeCompleteEvent) { </P>
<P> player.prefetch(); } </P>
<P> if(e instanceof PrefetchCompleteEvent) { </P>
<P> player.start(); } </P>
<P> if(e instanceof ControllerCloseEvent) {</P>
<P> player.stop();</P>
<P> player.close(); } </P>
<P>} 以上代码就可以实现捕获到本机的麦克并本机播放,自己就可以通过麦克听到自己的声音了,更多的基础知识请参考JMF基础教程</P><BR><BR>
