Although the articles getting a bit oldish, there still might be some ideas to be stolen borrowed from articles like Build a Digital Audio Workstation, Part I

I'm not really into audio much so I haven't checked; but there may be a more recent re-do of the subject. The magazine runs a regular series of DIY computerish projects.

(I thought that the recommendation of Win98SE as "possibly better" than more modern OS versions for home sound work was interesting.)
