Evaluation of the SMPTE X-Curve Based on a Survey of Re-Recording Mixers
Cinema calibration methods, which include targeted equalization curves for both dub stages and cinemas, are currently used to ensure an accurate translation of a film's sound track from dub stage to cinema. In recent years, there has been an effort to reexamine how cinemas and dub-stages are calibrated with respect to preferred or standardized room response curves. Most notable is the work currently underway reviewing the SMPTE standard ST202:2010 "For Motion-Pictures - Dubbing Stages (Mixing Rooms), Screening Rooms and Indoor Theaters -B-Chain Electroacoustic Response." There are both scientific and anecdotal reasons to question the effectiveness of the SMPTE standard in its current form. A survey of re-recording mixers was undertaken in an effort to better understand the efficaciousness of the SMPTE standard from the users' point of view.
