The condensor mic will also pick up everything else; the computer running in the background, your shoes shuffling on the floor, your HVAC unit, etc. But most importantly, it will pick up your voice echoing, reverberating or fluttering around in the room. When vocals are recorded in an untreated room, they will sound boxy.
To get really good sounding vocals, you'll have to acoustically treat the room. This is not the same as sound isolation. It will eliminate standing waves, echoes, flutter, etc. There's a lot to learn about it, so be sure to look over in the Studio Building forum and pick up what you can.
peace.
EDIT: Well, I got caught in the resurrected old thread trap.
Hey KJ09, please stop pulling up the old threads and posting the same advice. You've done it about 3 or 4 times now and pretty much cut and paste your replies. While no one minds if you bring up an old thread, just don't keep doing it and saying the same thing. Cool?? Thanks!!!
