How Do I...?

  • Use Effect Parameters

Retrieves and sets the value that specifies whether to swap left and right delays with each successive echo, in the EffectsEcho structure.

Definition

Visual Basic Public Property PanDelay As Integer
C# public int PanDelay { get; set; }
C++ public:
property int PanDelay {
        int get();
        void set(int value);
}
JScript public function get PanDelay() : int
public function set PanDelay(int);

Property Value

System.Int32
Value that specifies whether to swap left and right delays with each successive echo.

This property is read/write. 

Remarks

Can range from EchoEffect.PanDelayMin to EchoEffect.PanDelayMax.

The default value is zero, meaning no swap.

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);
