I pushed an audio file over -0dB in another program.
I then pushed a file over -0dB in Audacity and exported and then opened it as a new file and I was able to get an adjustment suggestion using the Amplify Effect. Maybe the way that clipped files are stored is different in a file generated by Audacity vs. other programs. Maybe Audacity files keep actual dB level in clipped files while other programs don't.

Ah - thanks Mike - that would explain why some of the WAV files offered the negative amplification and this doesn't. Many thanks for your prompt response. I use the program most days during the lockdown and it's. stoning piece of work. Well done to all concerned.

Audacity uses "32-bit float PCM" format internally. This format has benefits of not only great sound quality, but also the ability to support audio above 0dB.
Most WAV files are "16 or 24 bit integer PCM", which cannot go over 0dB (anything over 0 dB is simply clipped off).
