Edit the clip into the timeline. Park the blue position indicator on it, and enable the tracks with the clip(s) on them. Open AudioSuite (Tools>AudioSuite), and then select Time Compression/Expansion from the drop down menu. In the effect editor, there’s a slider you can move back and forth to make the audio longer or shorter (not in front of a machine, so I can’t remember the exact name of it). Render the effect and play it back and see how that sounds. If it’s too fast or slow, adjust the slider to make it slower or faster.
good luck,
