looking for sound editer

Is there an sound editor that can speed up and slow down a clip in the same way that Windows Sound Recorder works?

Audacity is one of the best sound editors around and it is also free!

http://audacity.sourceforge.net/

But why not just use Sound Recorder if it can do what you want it to do?

<double post>

I tried Audacity but it crashed every time I tried to set the output device to my speakers in preferences.

And the reason I don't use Sound Recorder is that I have a Mac ; )
