Wav Speed in VB6? 1

[roycejones]

Hi,

Does anybody know how to speed up a wav file in VB6, i'm looking to copy the function as in Sound Recorder (bundled with windows) where you select "Effects" then "Increase Speed".

thanks,

I'm guessing you are using PlaySound to play the WAV file. However, you are going to have to go much more low-level to achieve what you want. Here's an example

thanks a lot for that hypetia, thats exactly what I was looking for.

Now I have another question! Basically I want to increase the wav speed using the code provided in the other thread (works a treat!) But I now need to save the wav file, so the user clicks increase and the program saves a copy of the new file with an increase sample rate?

I'm not sure how to go about saving the file?

Thanks a lot.

This is exactly what the program does. It makes a copy of the original file, and sample rate changes are applied and saved permanently to the new file, keeping the original file intact. I hope the code is pretty much clear.
