reading data in C

I am taking a course about fourier and signal analysis, I already have a program in Turbo C++ that is able to read WAV files and then graph them for analysis. But I need for my final project to be able to read dynamically from my soundcard and not from a previously recorded WAV.
Should I use inportb(); to read from my soundcard and how do i figure out the soundcard's port #????
Any other ideas are also welcome.

Thanks

take a look at these pages... i dont have time to read them but one of them might help you
