Members Table
The following table lists the members exposed by the object.
Events
Event Description Disposing Occurs when the Dispose method is called or when the GargleEffect object is finalized and collected by the garbage collector of the Microsoft .NET common language runtime. Fields
Field Description RateHzMax Retrieves the maximum value for the EffectsGargle.RateHz property. RateHzMin Retrieves the minimum value for the EffectsGargle.RateHz property. WaveSquare Retrieves the value for a square modulation waveform for the EffectsGargle.WaveShape property. WaveTriangle Retrieves the value for a triangle modulation waveform for the EffectsGargle.WaveShape property. Methods
Method Description Dispose Immediately releases the unmanaged resources used by the GargleEffect object. Equals Returns a value that indicates whether the current instance is equal to a specified object. Finalize Allows the GargleEffect object to free resources before it is destroyed by the garbage collector. GargleEffect Initializes a new instance of the GargleEffect class. This method supports the .NET Framework Infrastructure and is not intended to be used directly in your code. GetHashCode Returns the hash code for the current instance. GetObjectByValue This member supports the infrastructure for Microsoft DirectX 9.0 for Managed Code and is not intended to be used directly from your code. op_Equality Compares the current instance of a class to another instance to determine whether they are the same. op_Inequality Compares the current instance of a class to another instance to determine whether they are different. raise_Disposing Raises the GargleEffect.Disposing event when called from within a derived class. Properties
Property Description AllParameters Retrieves or sets gargle parameters of a SecondaryBuffer object. Disposed Gets a value that indicates whether the object is disposed.

Remarks
Obtain this object by calling the GetEffects or GetObjectInPath method of a SecondaryBuffer object that is using the effect.

Add Effects to a SecondaryBuffer Object
This C# example demonstrates how to add effect objects to a SecondaryBuffer object.
[C#] //Create and setup the sound device. Device dev = new Device(); dev.SetCooperativeLevel(this,CooperativeLevel.Normal); //Create and setup the buffer description. BufferDescription buffer_desc = new BufferDescription(); buffer_desc.ControlEffects = true; //this has to be true to use effects. buffer_desc.GlobalFocus = true; //play sound even if application loses focus. //Create and setup the buffer for playing the sound. SecondaryBuffer buffer = new SecondaryBuffer( @"C:\WINDOWS\Media\ding.wav", buffer_desc, dev); //Create an array of effects descriptions, //set the effect objects to echo and chorus and //set it in the buffer. EffectDescription[] effects = new EffectDescription[2]; effects[0].GuidEffectClass = DSoundHelper.StandardEchoGuid; effects[1].GuidEffectClass = DSoundHelper.StandardChorusGuid; buffer.SetEffects(effects); //Play Buffer. buffer.Play(0,BufferPlayFlags.Default);
