hi lady sov,
if you've got yourself on cd or tape and your computer has a sound card all you have to do is record it into the computer, i don't know what kind of computer u have but it's pretty easy to do this. once you have a .wav or .aif of your CD or tape you need a program called Real Producer which you can get for free at
www.real.com (u have to really look for it because they put the free version at the bottom of the page in small letters.) when you have realproducer you can make your .wav or whatever into an .rm file. once you do that you can upload it to a webpage and then give people the web address where it is. also if you want to make it streaming then i think realproducer can do that as well.
hope this helps, i look forward to hearin ya. feel free to ask me more.
