Audio Delivery Specification

AES Convention 123 · Paper 7182 · October 2007

Abstract

From the quasi-peak meter in broadcast to sample by sample assessment in music production, normalization of digital audio has traditionally been based on a peak level measure. The paper demonstrates how low dynamic range material under such conditions generally comes out the loudest, and how the recent ITU-R BS.1770 standard offers a coherent alternative to peak level fixation.
Taking the ITU-R recommendations into account, novel ways of visualizing short-term loudness and loudness history are presented; and applications for compatible statistical descriptors portraying an entire music track or broadcast program are discussed.
