Please tell Dan I appreciated his presentation on Home Studio. In the short two hours he had he did a great job of getting to the two core issues for home studio related to gear and acoustics. He answered the questions what gear do I need and, more importantly, how much is it likely to cost me? Secondly, he spent some time discussing the two issues facing everyone in building a studio, sound isolation and sound treatment.
One of the things which might make a great add-on to this class would be a resource list of rock solid info to further extend the lesson. There's lots of info out there, but I would envision the list being a separating of the wheat from the chaff. Edge has a great resource on microphones and I have consistently referred to it as I search for the right mic for my budget. Another resource might deal specifically with the acoustical side of things dealing with the two issues mentioned above.
This class was a rock solid affirmation that tied together many of the things I have been reading about and viewing on the web. For instance, I've begun bookmarking what I think is useful on the web for VO and here is the start of my Acoustics bookmark file. I haven't picked up Dan's book yet, but had already purchased Paul Strikwerda's book Building a Vocal Booth on a Budget.
