Abstract: For decades, it has been widely accepted that a steady-state amplitude response measured with an omnidirectional microphone at the listening location in a room is an important indicator of how an audio system will sound. This paper examines both small and large venues, home theaters to cinemas, seeking a calibration methodology that could be applied throughout the audio industry. Room equalization schemes adjust the room curve to match a target believing that this ensures good and consistent sound. The implication is that by making in-situ measurements and manipulating the input signal so that the room curve matches a predetermined target shape, imperfections in (unspecified) loudspeakers and (unspecified) rooms are measured and repaired. It is an enticing marketing story. Copy @article{toole2015the,
