On the Road to Discovery!
KevinTran,
Sound cards come in so many different configurations it is a study in itself. But it is safe to assume most soundcards, if they have analogue ins and outs, are made for recording audio. They may not be made with very high quality components is all. Some cheap cards assume you will only be recording spoken word in lieu of a beautiful guitar or complex flute sound.
As to microphone type,whew! you may search the sticky thread in the microphone section for some involved answers, but an oversimplification is this: Dynamic mics (like Shure sm 57/58 ) are made for loud ballistic sounds that don't require really delicate capture of nuances and really high frequencies (think drums / guitar cabinets) and condensors are made for just the opposite. ( think- Acoustic sources like voice flute high frequency things like cymbal sheen etc)
Again ths is such a gross oversimplification it is laughable, but it will start you in the right direction.
Condensor mics are made where as they need to be powered generally from an external souce via 48 volts of phantom power usually furnished by your mixer or mic preamp. They also come with the diaphram in 3 basic denominations, small, medium(or mid),and large.
The small diaphram capsule is close in size to our eardrum and has approximately the same characteristics. It will make things sound very natural across the whole spectrum. These are ideal for capturing very realistic acoustic sounds true to their original sound.
The large diaphram models are made to paint a bigger than life picture of what you put in front of it and every mic has its own sonic signature. Like different spices or paint colors, some may be flattering while some may not.(think salt and sugar)
These are harder to recommend because they tend to hype / magnify and embellish different aspects so it is more important to audition these for a good fit.
The mid diaphrams are... well.. kinda in between. The Audio Technica 4033 is a good example. Sounds very good on a variety of sources from vocals to instruments. It may not be KILLER on any one particular sound source but good over a huge range of sources.
Anyway take what I say with a grain of salt. It is grossly oversimplified, and there are a HUGE number of exceptions to the rules. There are many dynamic mics the surpass Condensors in sound quality, etc.
Hope my rambling clears up a few points.
