How to clear up sound of an interview recorded through a dictaphone?

I recently recorded an interview with someone in a cafe. now i am having serious trouble trying to transcribe this interview due to the background noises. the background noises consist of people talking, moving, chairs, coffee machines etc.


is there any way i could make my recording more audible? listening to it is driving me crazy!How to clear up sound of an interview recorded through a dictaphone?
wash it thru winamp, and get a decent graphic equaliser (like 250 channels)





you can also use winamp plugins to slow it down and change pitch...
