Audio files are very large. A typical song stored as a .wav file can be easily 40 megabytes. The same song recorded in, or converted to, MP3 format would be smaller at roughly 7.25 megabytes, but that's still a large file. Anyway, if you plan on storing lots of music, you should have a large capacity drive or an extra drive for this purpose. You can always add an external USB hard drive for $100 or so, if needed.
If you are still running Windows 98 or ME you should really upgrade your PC to Windows XP. XP is so much more stable and smooth than Win 98 it's not even close. Of course, in order to upgrade, you should have at least an 800 megahertz processor and 512 megabytes of system ram. Remember: more ram = better performance. A 7200 rpm hard drive helps performance, too.
Laptop recording studios are quite popular these days as well, and with much of the available computer recording hardware being USB devices, a portable recording studio becomes a reality. The laptop does need to be fairly powerful though.
Now that Windows Vista is out, I thought it would be a good idea to include some information on it. First of all, you're going to need even more power and ram for Vista. Since the vast majority of home users running Vista will be using either Home Basic or Home Premium, let's limit our analysis to those two.
The basic differences between the two are:
1. Vista Basic does not have the "Aero" interface with transparencies and effects
2. Vista Basic does not have all the added multimedia features
I would recommend the minimum specifications shown below. This would allow you to run any of the software advertised on this site. Obviously, this is only a guide since not all recording software will require these specs, but they will allow you a little extra performance and room to grow. If your computer doesn't meet these specs, don't fret. Simply pick the software that will run on your setup and go with it.
1. 1.6 Ghz. Pentium III or Athlon cpu
2. 512mb ram
3. 40gb 7200 rpm hard drive
4. 32mb AGP video card
5. On board AC97 audio or separate soundcard
6. 24X CDRW drive
7. Windows XP (home or professional) with service pack 2
