Methods

Method	Description
Dispose	Immediately releases the unmanaged resources used by the WavesReverbEffect object.
Equals	Returns a value that indicates whether the current instance is equal to a specified object.
Finalize	Allows the WavesReverbEffect object to free resources before it is destroyed by the garbage collector.
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 WavesReverbEffect.Disposing event when called from within a derived class.
WavesReverbEffect	Initializes a new instance of the WavesReverbEffect class. This method supports the .NET Framework Infrastructure and is not intended to be used directly in your code.

Properties

Property	Description
AllParameters	Retrieves or sets Waves reverb parameters of a SecondaryBuffer object.

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);
