Hello everyone, my name is Gianluca and I'm writing from Italy. I turned a basement into a recording studio, but I need a hand to the acoustic treatment. Floor, ceiling and walls are covered with wood. Under the wood there is a layer of lead, polystyrene and moisture resistant material. The dimensions are: Length: 4m Width: 2.56mt Height: 2.7 meters I would like to build all by myself (DIY) with a budget of EUR 800 I hope I have said it all. Attached is the floor plan of the study and a photo of the current positioning of monitors I have totally no experience in the field of acoustic treatment, can you help me??
