Chewie, first of all the answers to your questions - Cool Edit is a multi-track program, so you can therefore record multiple tracks. Sound Forge is a STEREO editor, so NO - you can't record multiple tracks, unless your definition of multiple is only TWO.
Before I make my next point, a little background so you hopefully don't take offence (this happens a lot with newbies, since most are young and generally self-centered even when trying NOT to be) (I know this, having a good memory, even though I'm now old enough to have INVENTED DIRT)
Anyway, my point to ALL newbies, not just you, is ECONOMY OF TIME.
What do I mean by this? Those of us who try to help new-comers to recording, only have so much extra time (if any) and that DOESN'T include the time it takes to answer the same questions over and over and over....
This is why we post LINKS, such as the excellent ones SPINSTERWUN has posted for you. If you had followed several of these links, a lot of the questions you have would have been answered, saving at least two people enough time to either GET A LIFE or help someone else who may have already tried finding information that's already available BEFORE posting questions that could be answered with a little research.
For example, looking on ANY music sales website that handles software will get you the name of the company that produces Sound Forge (it's sonic foundry, BTW) so if you type in sonicfoundry for the URL you will get to their website. A click or two on products will take you to a description of their offerings, and by reading the text you would see that Sound Forge is called a STEREO editor. Its main function is for editing STEREO tracks, as in mastering AFTER mixdown. The newest version, from what I've read, also once again includes CD burning capabilities, so it could also be used as a high end do-everything CD burning software.
There have been a few newbies that, at this point, have taken to swearing at all of us here, thinking (in their supreme egotism) that we have ALL THE TIME IN THE WORLD to answer every question everyone has about everything.
I'm hoping you're more mature than that and can see OUR SIDE of this - NONE of us have enough time in the day to spend this much of it on anwers that can be found with some well-directed research. Try putting yourself in our position and see if you don't agree on this.
This is NOT meant as any kind of put-down, so please don't take it that way - My goal here is to help you learn how to research the things you're interested in, without having to be spoon-fed every step of the way.
Most of the time, if you know where/how to look and HOW TO READ what you find, you can get answers to most of your questions FASTER than waiting for a personal answer.
One helpful tip: When looking at information on a website or catalog description, remember that it comes from SOMEONE WHO IS TRYING TO SELL YOU SOMETHING. What this means, is that they will BRAG about ANYTHING and EVERYTHING they possibly can, in order to SELL their product. Sooo, if they DON'T mention a particular capability, it pretty much GUARANTEES that they DON'T HAVE IT !!! Case in point - Sound cards that really talk up 24 bit, but say NOTHING about 96 k Sample rates - guess what? IT AIN'T THERE !!!
It takes a while to learn to read ad copy pessimistically enough to weed out the bullshit, but once you learn that, you can tell a LOT about a particular piece of gear by what they DON'T say.
It took me about 10 minutes to compose and type this answer, and that is time I could have used to help 2 or 3 other people, or work on the design for my own new studio complex. That's why I anwered at all, because hopefully this will help you find more information through RESEARCH and study. If so, I promise you that you'll LEARN more (and sooner) and FEEL more accomplished than you ever would by just asking questions as they pop into your head, and waiting for the answers.
Again, this is NO WAY intended as any kind of put-down, only as a direction for you to take on your own path of enlightenment, whether in the field of sound and recording or anything else that interests you. Research is a lot like sales - you just keep looking until you find the answer you want.
Please, go back and follow more of SPINSTERWUN'S links, read a lot, and you'll find you have deeper questions but at the same time more knowledge.
The internet is a goldmine of information. Use it well and there is no end to what you can find... Steve
