Converted to stereo, added a touch of brilliance, and applied noise reduction.

Answer #3
Thanks a lot! I see it’s very hard to make it sound better.
What applications did you guys use? Again, thank you very much
Answer #4
Sound Forge
If I worked on it for several hours straight, I could probably make it sound clear and decent. Like Carole King maybe?
