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 DistortionEffect object is finalized and collected by the garbage collector of the Microsoft .NET common language runtime.

Fields

Field Description
static (Shared in Visual Basic) EdgeMax Retrieves the maximum value for the EffectsDistortion.Edge property.
static (Shared in Visual Basic) EdgeMin Retrieves the minimum value for the EffectsDistortion.Edge property.
static (Shared in Visual Basic) GainMax Retrieves the maximum value for the EffectsDistortion.Gain property.
static (Shared in Visual Basic) GainMin Retrieves the minimum value for the EffectsDistortion.Gain property.
static (Shared in Visual Basic) PostEqBandwidthMax Retrieves the maximum value for the EffectsDistortion.PostEqBandwidth property.
static (Shared in Visual Basic) PostEqBandwidthMin Retrieves the minimum value for the EffectsDistortion.PostEqBandwidth property.
static (Shared in Visual Basic) PostEqCenterFrequencyMax Retrieves the maximum value for the EffectsDistortion.PostEqCenterFrequency property.
static (Shared in Visual Basic) PostEqCenterFrequencyMin Retrieves the minimum value for the EffectsDistortion.PostEqCenterFrequency property.
static (Shared in Visual Basic) PreLowPassCutoffMax Retrieves the maximum value for the EffectsDistortion.PreLowPassCuttoff property.
static (Shared in Visual Basic) PreLowPassCutoffMin Retrieves the minimum value for the EffectsDistortion.PreLowPassCutoff property.

Methods

Method Description
Dispose Immediately releases the unmanaged resources used by the DistortionEffect object.
DistortionEffect Initializes a new instance of the DistortionEffect class. This method supports the .NET Framework Infrastructure and is not intended to be used directly in your code.
Equals Returns a value that indicates whether the current instance is equal to a specified object.
Finalize Allows the DistortionEffect 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.
static (Shared in Visual Basic) op_Equality Compares the current instance of a class to another instance to determine whether they are the same.
static (Shared in Visual Basic) op_Inequality Compares the current instance of a class to another instance to determine whether they are different.
raise_Disposing Raises the DistortionEffect.Disposing event when called from within a derived class.

Properties

Property Description
AllParameters Retrieves or sets distortion parameters of a SecondaryBuffer object.
Disposed Gets a value that indicates whether the object is disposed.

How Do I...?

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);
