ABSTRACT
Calibration of the acoustic sound levels has been a requirement for many years when working with sound for film, although it has not been particularly common in other branches of the sound industry. However, with the widespread use of multichannel formats for all forms of music and film presentation in the home, it has turned out to be beneficial to also calibrate the acoustic levels for these formats. The channels can carry independent and uncorrelated audio signals. The format has proven efficient for natural, microphone-based immersive recordings. The national broadcaster of Japan, NHK, developed a configuration for Super Hi-Vision, a format with much higher resolution than standard High Definition. Dolby Atmos is a format for the cinema – and the home – that takes advantage of object-based audio. The goal for Digital Cinema is the establishment of completely file-based formats to be distributed by data networks.
