I do not think that it is ruined. Something has gone wrong certainly.
Do you have any recent back-ups you can load and check out?
Can you reset the Items' Playback Rates back to 1?
Also, start a new project and load those audio recordings - and check that they are OK. If so, then we can start fixing the problem project.
