Delphi Libraries

Hi all,
       I'm currently doing a final year project which basically involves
the conversion of data to sound and vice versa.  I'm looking for a delphi
library which lets me generate sound so that i can convert data and
transmitt it through the sound card!  If anyone can help me i'd be most
appreciative and if you ever over in Ireland i'll bring you out for a stiff
pint of Guiness.

Mike from Ireland!
