Changing frequency in a wav file

Is it possible to change the frequency of a .wav file in VB3 and if so - how ?
Thanks

I dunno if DirectX works with VB3, but using DSound you can change such things of wav files...

I know it's possible with the API, because I've seen examples and I have a project that does it. However, I haven't really looked at it, so I couldn't tell you off the top of my head. Search the internet and you'll eventually find something.

Do you want to alter the file itself or simply play it back at a different rate?

Hmm, you could just change the frequency in the toc part of the wav file;

I want to play the .wav file back at a different rate.

If you're using the wave stream functions, set the frequency to what is thould be played at, keeping the data the same.
