NEWS YOU CAN USE: Video on How to Make Your Bedroom Studio Sound Great, from Russ Berger, Gavin Haverstick, and Sweetwater’s Mitch Gallagher (Video):
I know from talking to all three men that they definitely know their stuff when it comes to acoustics. I would also add that if you’re recording using a drum machine and/or pre-recorded drum loops and guitar modeling gear and/or software synthesizers and just recording your vocal tracks live, a Reflexion filter and some duvets on the wall behind the singer (and perhaps on the ceiling as well) can do wonders to tame some otherwise pretty crappy sounding rooms. (It works equally well for recording a podcast, or voice-over narration, incidentally.) Any additional steps in sound treatment to make a room sound better will often pay far more dividends when recording than thinking that an expensive microphone without any room treatments will do the trick.
