Hi there. I am looking for a way to make the room I record in, as sound proofed, "treated" as possible, for as cheap as possible. I live in a really quiet area (it's basically silent during the day) and the room I will be recording in is a utility room in my garden, about 1 metre from the house. There is double glazing glass on the room's windows/door and the windows to the house. Preferably I would like not to be heard from the house.. (This will not need much work because it's quite hard to hear at the moment, but i would like it to be possible not to be heard at all) My second concern is to not be heard by neighbours. I've heard hanging carpet or duvets on the walls is good? Like I said, I would like this to be as cheap as possible. REgards.
