AES17 defines a digital Full Scale and 0 dB FS as the level of a sinewave whose peaks reach the largest positive digital code. Some incorrectly display full scale sinewaves as -3 dB FS. The AES17-2020 revision is an effort to eliminate this confusion.
Originally released in 1991, AES17 introduced and defined the measurement of 0 dB FS. This definition has remained unchanged through revisions of the standard in 1996, 1998 and 2015. The 2015 revision added notes to clarify the proper calibration of dB FS. The 2020 revision further expands on these notes.
The 2020 revision will be available for download on 2020/12/11
