but only a miracle by someone who is very knowledgeable and skilled can save audio recordings that are very flawed.

They do it on TV all the time . . .

From what I have read and experienced, noise removal is best accomplished in multiple subtle passes instead of trying to do it all at once. Even better is doing it with several different tools. Also, it is always better to do too little than too much. 

Multiple passes with a few db removal. If it’s a sample learning app, pick a different section of noise each time. Also, vary the settings slightly each pass. Don’t use the same settings 5 times. 😉

Have you tried an EQ sweep with very narrow Q to identify and then remove the frequencies?
