Using DirectSound to play segment of .wav file

Hi there,

I need to be be able to take a .wav file and play only part of it eg from 200 to 800 ms through the file. I have code that will do it using DirectShow, but I'd like to do it in directSound. Also, I can play the whole file using DirectSound, based on the examples in the SDK, but I don't know how to just play part of it. Is it possible?

I'm using Visual C++ .NET 2003 IDE to write native C++ code, if it makes a difference.

Thank you.

You can load the full wav file into a static buffer (usually, a small one) or use streaming and callback functions to load parts of the file as they are needed.
You can start from here:

To play part of it, load the approriate section of the file into a buffer or simply pass an offset to Play.
