EffectsParamEq Structure (Microsoft.DirectX.DirectSound)
Contains parameters for a parametric equalizer effect.
Visual Basic Public Structure EffectsParamEq C# public struct EffectsParamEq C++ public value class EffectsParamEq sealed JScript In JScript, you can use structures, but you cannot define your own.
The following table lists the members exposed by the object.
Methods
Method Description EffectsParamEq Initializes a new instance of the EffectsParamEq structure. ToString Obtains a string representation of the current instance. Properties
Use Effect Parameters
This C# example demonstrates how to use the parameters of an effect object from a SecondaryBuffer object.
The buffer object in this code snippet is assumed to be the SecondaryBuffer from the code in Add Effects to a SecondaryBuffer Object.
[C#] //Retrieve the effects object and //the effect param sturctures and edit parameters. EchoEffect echo = (EchoEffect)buffer.GetEffects(0); EffectsEcho echo_params = echo.AllParameters; echo_params.LeftDelay = 250.0f; echo_params.RightDelay = 100.0f; echo_params.Feedback = 85.0f; echo_params.PanDelay = 1; echo_params.WetDryMix = 50.0f; ChorusEffect chorus = (ChorusEffect)buffer.GetEffects(1); EffectsChorus chorus_params = chorus.AllParameters; chorus_params.Delay = 15.0f; chorus_params.Depth = ChorusEffect.DepthMax; chorus_params.Phase = ChorusEffect.PhaseNegative90; chorus_params.Waveform = ChorusEffect.WaveSin; chorus_params.WetDryMix = 50.0f; //Set the new parameters and play the buffer. echo.AllParameters = echo_params; chorus.AllParameters = chorus_params; buffer.Play(0,BufferPlayFlags.Default);
