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);
