Need to be able to read sound file length, which could be something like [url removed, login to view] seconds and make it 5 seconds by padding out with silence after the sound. It would need to always pad out to nearest (upwards) full second.
It will be for use in a .net 4.5 winforms project. I will run it across all sound files in a folder and then it will overwrite the existing file. Files are in .wav format.
