Capturing a sound consists of the following steps:
1. Start the buffer by calling the Idirectsoundcapturebuffer8::start method. Formally, you should set dscbstart_looping as the dwflags parameter so that the buffer will continue to run instead of stopping when it reaches the end of the buffer. The audio data obtained from the input device is populated starting at the beginning of the buffer.
2. Wait until the desired amount of data is reached. A decision on when to
You can use the Idirectsoundcapturebuffer8::getcaps method to get the size of the "capture buffer". Make sure that the dwsize member of the struct is initialized before using the DSCBCAPS structure as a parameter pass.
To get the format information when the buffer is created, you can call the Idirectsoundcapturebuffer8::getformat method. This method returns the format information in the form of a WAVEFORMATEX structure body.

You can create a capture device object by calling the DirectSoundCaptureCreate8 or DirectSoundFullDuplexCreate8 function. Both of these functions get a pointer to the IDirectSoundCapture8 interface.
The Lpcguid parameter of the directsoundcapturecreate or the Pcguidrenderdevice parameter of the DirectSoundFullDuplexCreate8 can be a GUID obtained by the enumeration, Or one of the following predefined GUIDs:
