Home studio, Materials for Vocals recording

I think that equipment should do ok. I dont have exact specs in front of me but things to look for is does the interface have

a.phantom power

b.zero latency monitoring

c.24 bit a/d convertor

*optional* ability to record up to 96k sample rates

IF what your buying cant do all the above you might wanna keep shopping.

Vocal Booth - This will make a big deal to your sound.  I have seen all fashions of this man.  When I first come up I would just clean out a closet,remove the rack/bar and use a staplegun to adhere blankets to the wall and run headphone wires in there........to now I have made several professional looking booths complete with a flat screen monitor and key board and mouse and headphones to control yourself in the booth.

The difference in sounds?   While a professional booth and egg crate sound foam certainly looks better from an aesthetic point of view I cannot sit and here and say it sounds night an day better.  To me it sounds a hair more refined but the ole closet with blankets sounded about as good.   For what your doing voiceovers and a little singing I would prolly do the closet but the monitor and keyboard/mouse access is mandatory now IMO.  There is nothing quite like pressing "R" on the keyboard and sprinting in the closet and putting your headphones on and then hope you get a good take!
