Hi,Apologies for not replying sooner.
I'm not sure if you mean between different projects but you can cut and paste segments of the audio track within a single project.
Left Click on the audio track and Drag Out the area you require.
Right Click and choose Copy.
Then Right Click on the new position on the timeline and choose Paste.
A copy of the selected audio will then be placed at a new position on the timeline.
I hope this is of some help.
Pete
