AES5-2018 (r2023): AES recommended practice for professional digital audio - Preferred sampling frequencies for applications employing pulse-code modulation (revision of AES5-2003)

Printing Date: 2018-12-02

Publication History: Pub. 1984; Rev. 1997; Rev. 2003; Rev. 2008; Reaff. 2013; Rev. 2018; Reaff. 2023

Abstract: A sampling frequency of 48 kHz is recommended for the origination, processing, and interchange of audio programs employing pulse-code modulation. Recognition is also given to the use of a 44.1-kHz sampling frequency related to certain consumer digital applications, the use of a 32-kHz sampling frequency for transmission-related applications, and the use of a 96-kHz sampling frequency for applications requiring a higher bandwidth or more relaxed anti-alias filtering. This revision further quantifies the preferred choices for higher sampling frequencies. (8 pages)
