specified bandwidth. Dynamic Range is a signal-to-noise ratio measurement over the specified
bandwidth made with a -60 dBFS signal. 60 dB is added to resulting measurement to refer the
measurement to full-scale. This technique ensures that the distortion components are below the
noise level and do not affect the measurement. This measurement technique has been accepted
by the Audio Engineering Society, AES17-1991, and the Electronic Industries Association of
Japan, EIAJ CP-307. Expressed in decibels.
