It’s a great start and should improve the overall sound. I’d skip the door unless you have a need to see the outside though, or make it look really professional. I do my voice stuff with just the blankets and it goes a long way. It’s not perfect, but it’s a lot better than an open room (no traffic noise, no air conditioner hum, for example). Plus I don’t need a glass door since it’s just me.
But when you say distortion, what is causing that? Echoes? Distortion is a word that (to me) means recording issues more than ambient sound.Just wondering. Just make sure there’s not some other issue.
But overall i say go for it.
