Speed of audio file

Dear All,
we have new WaveLab9 at work (before we had 6) and I am just an amateur, knowing just some basic steps. Sorry for probably stupid question.

We work with long audiofiles - we need to listen them and cut them. In WaveLab6 there was an option to speed up playing/viewing the audiofile without changing its speed at the end. Does WaveLab9 have the same and where to find this feature? I just found “Time stretching”


This function is still available. Click on the extension button on the Transport bar.


Hi Philippe,
I tried this function,but not sucesfully. Could you please give me more details? (Sorry, I need explanation like “For Dummies” :slight_smile: )
Have a nice day,
