Project file fades out

Windows 10
Audacity 2.1.3
exe install

How do I fix a file that steadily fades out. It is a 45 min podcast file and at some point I exited and saved with the fade out effect in place. I tried to fade in creating the eyeball looking wave and then tried to amplify. No luck. Really new to audacity so any help is appreciated.
