In this episode I walk you through the incremental improvement that each layer of acoustic treatment modules made in this home studio transformation. The rear wall modules, the side wall modules, the front corner bass traps, and the ceiling cloud are all analyzed. We go over the All SPL and phase / frequency response graph, the Impulse / ETC graph, the Filtered IR Graph to see decay times by frequency, the Waterfall graph, and the Spectrogram graph.

It’s a full step by step analysis of detailed acoustic testing from REW. You can use the same process to test and evaluate your home studio as you build DIY sound panels.
