My HS buddy's girlfriend has asked me to record voice passages for some promotional work she is involved with. Small projects that probably will never see national exposure, but will be shopped to certain national retailers, so you never know. I own a MD421 and a Studio Projects C3, that should be adequate. Also have a clean mic pre, RNC compressor, Lexicon fx and A/D converter, and a Roland digital recorder. What else would you recommend? Room treatments? My studio is a plaster-walled second story bedroom with a barrel vaulted type ceiling. Has thick carpeting. Will probably buy a pop screen. Any recommendations about voice eq, compression? My lexicon fx has plate and ambience/chamber type simulations. Any ideas or comments welcome. Thanks.
