HELP! Strange clipping in audio file

Hello friends, I come to you with a disaster: one of my raw radio files has a bunch of strange clipping noises in an extensive part of it (maybe up to an hour!) I have no idea what caused this - this seems to be the only time this has happened. Maybe my mic was loose when I was making the recording.

However it got here, I have to clean it up. I’m using Adobe Audition; if anyone has any tips or suggestions about how you’d approach a problem like this one, I’m all ears. Thanks in advance!

You can hear the problem happening in this clip here, and you can see a picture of the waveform with the problem below:
