96k frame

MADI sources with a sample rate of 88.2kHz or 96kHz can be configured to use the so-called 96k frame. If this frame is used, a sample rate of 88.2 or 96 kHz can be detected on the receiver side automatically. When it is not used, or when higher sample rates are used, the receiver must always be configured to the correct factor (x2, x4) since there is no other mechanism in MADI that allows automatic detection.


Audio Video Bridging (AVB) is a common name for the set of technical standards developed by the Institute of Electrical and Electronics Engineers (IEEE) Audio Video Bridging Task Group of the IEEE 802.1 standards committee.


IEEE standard for device discovery and control. A protocol that is used by manufacturers to control various settings of AVB endpoints.

ATDECC Controller

A software that discovers AVB entities and allows the user to access their settings and connect them. Different ATDECC Controllers from different vendors can be used at the same time in the same network.

AVB talker

An AVB endpoint that streams audio to one or more listeners.

AVB listener

An AVB endpoint that receives an audio stream from a talker.

Double speed

A sampling rate of 88.2 kHz or 96 kHz (compare single speed and quad speed)

DHCP server

A DHCP Server hands out IP addresses to network devices. Every consumer oriented WiFi Router has a default DHCP Server handing out private addresses, usually 192.168.0.x. The IP address of a network device must be known in order to communicate with it on Layer 3.


Multichannel Digital Audio Interface as defined in the AES 10 standard. Used to receive and transmit up to 64 uncompressed audio channels over coaxial or fibre optic connection.

Quad speed

A sampling rate of 176.4 or 192 kHz (compare single speed and double speed).

Single speed

A sampling rate of 44.1 kHz or 48 kHz (compare double speed and quad speed).

Word Clock

An electrical square wave signal transported over coaxial 75 Ohm terminated cables. It is used to synchronize the receiving device (slave, word clock input) to the sending device (master, word clock output).
