I am setting up a home studio in an empty closet with a dynamic or condenser microphone. Recordings have some echo and I would like to reduce reverberation time by about 75% to be barely noticeable. The walls are hard and parallel, so wall treatment with absorbers is the way to go (from Home Studio Echo Problem). I would like to do it with between $50 and $100.
I am considering the following options:
- covering surfaces with blankets, duvets, or comforters
- covering surfaces with "acoustic geo textile" (literal translation from Portuguese, product here) with 5mm, 10mm or 20mm thickness
- surrounding the microphone with a foam vocal booth, a cube with one side open for the actor's voice (product here)
Covering surfaces with acoustic foam tiles is not practical, as it would damage the walls and doors.
Which of these, alone or in combination and in which thickness, are most promising to reduce reverberation time?
