在开始工作之前，要先介绍DirectSound录音用到的三个非常重要的对象，IDirectSoundCapture8 ，设备对象，根据你录音的设备创建的设备对象，利用该对象可以获取设备的属性。IDirectSoundCaptureBuffer8，缓冲区对象，该对象由设备对象创建，主要用来操作音频数据IDirectSoundNotify8 ，事件通知对象，该对象用来通知应用程序从缓冲区中将数据取走，写入文件保存起来。利用DirectSound录音的主要思路，就是先根据选择的录音设备创建设备对象，然后通过设备对象创建辅助缓冲区对象，开始录音的时候，设备将数据写入缓冲区，应用程序主动的从缓冲区将数据读出来写文件即可，就实现了录音功能。这里简单介绍一下dsound的通知功能，应用程序会创建一个通知对象，然后将通知对象邦定，然后设定通知位置（position），什么是通知位置呢，比如缓冲区的大小为4000字节，如果你想当数据达到缓冲区一半的时候能得到通知开始copy数据，那么此时你就可以将通知位置设定为2000，通知位置可以任意的设定，当缓冲区的数据达到你设定的位置时，就会通知应用程序将缓冲区的数据copy到文件中，缓冲区是循环利用的，当缓冲区填充满了以后，就会从头开始充填数据，所以，缓冲区就是一边读，一边写的过程。
