Michael Minetree calls it The Monster Sound Isolation Booth and I would heartily agree. At his site, Michael has provided a detailed and inspiring photo journey through the process of building a first class isolation booth for voiceover or instrument recording.
Take the tour starting here. I think you’ll be as impressed as I am.
(edited to update URI of link to new blog structure at Michael’s site)
it sure is a monster, but one thing that was glaringly omitted (unless I missed it in the myriad pictures) was ventilation, there seems to be none.
Bill,
He doesn’t say a lot about ventilation, you’re right. In the middle of the 4th page is the only place Mike mentions it.
Be well,
Bob
