Conference Paper

Dynamic Range Issues in the Modern Digital Audio Environment

Authors: Fielder, Louis

AES Conference: UK 9th Conference: Managing the Bit Budget (MBB) · Paper MBB-02 · May 1994

Abstract

The peak sound levels of music performances are combined with the audibility of noise in sound reproduction circumstances to yield a dynamic range criterion for noise-free reproduction of music. This criterion is then examined in light of limitations due to microphones, analog to digital conversion, digital audio storage, low bit-rate coders, digital to analog conversion and loudspeakers. A dynamic range of over 120dB is found to be necessary in the most demanding of circumstances requiring the reproduction of sound levels of up to 129dB SPL. Present audio systems are shown to be challenged to yield these values.
