Need recipie suggestion to clean up mp3 voice recording done in 1954

I have two mp3 files of an interview done in 1954. I found this on an Internet archive and don’t know what has happened from 1954 to now. The audio is very poor quality and difficult to understand. Any recipe suggestions or help appreciated. ~ Amy

tried the software… it certainly cleaned up like the some noise, but turned most of the audio to gibberish. I think is probably because the audio is so bad to begin with.
