Slowing down audio

I am using WL LE to to edit imported audio files of me doing some guitar playing. I did a recording recently and noticed a loud click on the recorded track…must have been something in the room.
Anyway, because I couldn’t work out how to slow down the tempo of the recorded audio file, it was really hard to catch the click and cut it from the recording.
The question is, is there a way to slow down an audio recording so that I can catch the background noise and remove it from the recording.

Sorry, WaveLab LE does not allow this.

Can you think of a workaround?

Kind Regards
