NewBie here ,Can someone help me ??

Hi all, I am familiar with .NET Framework and uses C# as my language.Anyway i am interested in learning the DirectX SDK and its programming and i mainly want to program something like giving effects(BASS,TREBBLE,etc blah blah) to some sounds etc.I have read the documentation given by Ms along with the Managed SDK.I tried to learn something from that and i startted with DirectSound.I read the possible documentation( tat was really crude stuff ) and i could understand only onething-To play a sound create a device,create a secondary buffer and provide the device to it and then describe the buffre and play the loaded file.But i couldnt understand wat exactly the BufferDescription is???Is there any way to start in a better fashion instead of learning from the Documentation.Can someone provide some links please.Thanks all.
