I seriously doubt that Software is going to make for poor quality recordings. Digital pretty much IS what it is. The weak link is more probably getting what you hear in the room into the darn computer. If your mic is decent, i.e. if you recorded to a plain old tape machine and that sounds good, then it's just how to translate from mic (analog world) to PC (digital). There are dozens of solutions out there, generally involving a USB or Firewire output to hook to your PC (Digital) and some kind of mic-pre on the other for your Analog Mic. I've used the Tascam gadget for the last few years with good success, but again, it's just one solution out of many. It only has two mic inputs. However If I put my Mackie Mixer in front, that no longer becomes limiting.
This is what I've been using, there is a newer model available now. My software is very basic, Shareware product called Audacity. It's easy to use and basically free to try. Download a copy and try it before you spring for more expensive software. That my 2 cents.
