convert to another type of file

I have spent a lot of time recording family cassettes with audacity thinking that we could copy to a cd and play on a cd player. I destroyed the old cassettes when I was through. What can I do to make these files play on a computer without audacity or a cd player? I am desperate. These were recordingS of long dead people in my family and are irreplaceable. HELP !!!

To create an ordinary audio file from an Audacity project use “File menu > Export”.
