- DirectShow Sample -- GargleDMO
- ------------------------------
-
- Description
-
- This sample is a Microsoft DirectX Media Object (DMO) that creates a
- gargle effect, similar to the Gargle Filter sample for Microsoft DirectShow.
-
- This sample demonstrates how to implement the the following interfaces:
-
- IMediaObject
- IMediaObjectInPlace
- IMediaParamInfo
- IMediaParams
-
-
- User's Guide
-
- To use this DMO, build and register GargleDMO.dll. The sample project builds
- several intermediate libraries. To build the DLL in Microsoft Visual Studio,
- select Batch Build from the Build menu.
-
- You can use the DMO in the DMO Demo sample application, or with the
- DirectShow GraphEdit utility. GraphEdit automatically wraps the DMO in the
- DMO Wrapper filter.
-
- You can also use the DMO in Microsoft DirectMusic applications, including
- the Microsoft DirectMusic Producer application included with the SDK.
- In DirectMusic Producer, use the Audiopath Designer to insert the DMO into an
- audiopath. To control media parameters, use the Parameter Control track.
- Insert a curve in the track and assign it to control any of the properties
- on the DMO. For more information, see the Audiopath Designer and Parameter
- Control Track topics in the DirectMusic Producer application help.
-
- The Gargle DMO provides a property page for the user to set the shape of the
- modulating waveform (square or triangular) and the frequency. It also supports
- a custom interface, IGargleDMOSample, for setting these properties.

- For more information about this sample, see "DirectShow Samples" in the
- DirectX 8 SDK documentation.
