Faster Speed For QSound-object

[QT_NUB]

I'm having a QSound-object which contains .wav-audiofile. Its length is 3s. In some situations I want it to be squeezed to 1.5s. How I play it at double speed? If QSound doesn't do that, in which way I do it then?

The easiest way would be to have a second file, e.g. created from the first with an audio manipulation program.

...and the more difficult case? I like challenges.
