Multichannel Audio Digital Interface,
MADI or
AES10 is an
Audio Engineering Society (AES) standard electronic
communications protocol that defines the data format and electrical characteristics of an interface that carries multiple channels of
digital audio. The AES first documented the MADI standard in AES10-1991, and updated it in AES10-2003 and AES10-2008. The MADI standard includes a bit-level description and has features in common with the two-channel format of
AES3. It supports
serial digital transmission over
coaxial cable or
fibre-optic lines of 28, 56, or 64 channels; and
sampling rates of up to 96 kHz with
resolution of up to 24 bits per channel. Like
AES3 or
ADAT it is a Uni-directional interface (one sender and one receiver).
