Home Recording Connection is a site I stumbled upon this evening. It’s filled with interesting ideas. Some are better than others, but one that I thought especially worthwhile is this article about how to sound proof your garage on a budget, thus turning it into a studio.
In the case of this article, the writer was building out his garage to use as a practice studio for his rock band; but the ideas will work just as well for making a quiet space to put your home voiceover studio. What I especially like is that the article is filled with ideas about how to do this build-out for very little cost.
(edited to fix typo. Thanks Chris Eder for helping me with that one.)
