You probably already know that your room affects the quality of your home recording. Sound is airborne waves which are physical in nature and are thus affected by physical structures. Sound waves in rooms are affected by walls, floors, ceilings, curtains, furniture, televisions, light fixtures, and other. In short, anything that obstructs the path of the sound wave will alter it and will ultimately change the sound that our ears perceive. The end effect of this may be desired or undesired. Typically, since the human ear is used to hearing sound after such room resonances, those may make the sound appear more "natural" and "lively". This is why recording engineers artificially introduce room resonances in sound recordings through reverb units. Without them the recording will sound "dry" and unnatural. So why exactly are our room resonances problematic?
