Doing my first home-brewed CD, and decided for several reasons to use sound-absorbing blankets. My bass and guitar tracks will be recorded line in. I need sound blankets for vocals and anything else that requires a mic. Drums will be recorded elsewhere. I'm on a shoestring budget. I'll likely hang them from room partitions. I can move them into position that way. Will also keep the landlord happy; no holes in the walls. Any final words of wisdom from someone who has successfully used this technique?
I'm also uncertain as to whether I need to treat these (Producers Choice) with fire retardant?
