So I did some digging around and found some cool recording software that is cheap or free.
First the DAW (Digital Audio Workstation) that can be run from a thumbdrive cost money, but not much. It’s called Energy-XT
The next that is free and runs on Windows 98 is Reaper.
And don’t forgot good old Audacity.
Now any computer can record audio, Apple, Windows, Linux. Most people prefer using the Mac because it comes with a great DAW Garageband. Garageband is pretty and probably the easiest to learn and use. Also Apple uses it’s own audio drivers called Core Audio, what this means to the user is that setting up audio interfaces and getting them to work is just a few clicks away.
If your using Windows machine and buying a audio interface make sure you have the right driver for your version of windows and read all the instructions that come with the interface. Also setting up the interface can sometimes be a huge pain but once you get it to work should be good from then on.
