Routing

The Routing tab provides a detailed view of audio mappings within the AVB domain, offering both listener and talker perspectives.

This tab is only shown in Streams mode; it is not available in Channels mode. For Channels mode, see Channels mode.

General Concepts

Stream Name

Modify stream names by right-clicking on a stream and choose 'Edit stream name'.

Listeners	Talkers

Channel Name

Modify channel names by left-clicking on them.

Mapping

To map audio channels from or to a stream, expand streams and channel groups and click on the matrix crosspoint to connect or disconnect.

	Click to set up a mapping.
	Mapping is established.
	Click to dissolve a mapping.

Mapping for Talkers

Interrupts audio while streaming

Modifications to the talker mapping temporarily interrupt audio while streaming. To prevent accidental interruption, editing must be started explicitly by clicking the 'Edit' button in the upper right corner of the tab.

To apply the changes, confirmation must be provided using the 'Apply' button.

Diagonal Mapping

Diagonal mapping applies or removes a full diagonal series of channel-to-channel mappings in a single click, instead of setting up each mapping individually. When an intersection is clicked while holding the Ctrl key (Windows) or the ⌘ key (macOS), routing is either applied or removed diagonally, terminating at the lower end of the matrix.

The resulting modification is visually indicated prior to the establishment or removal of the connections.

Similarly, when the Shift key (Windows and macOS) is held while clicking an intersection, routing is applied or removed along a diagonal path that wraps around until the right end of the matrix is reached.

As with the previous method, the change is visually indicated before the connections are established or removed.

Collapse / Expand All

All streams and input/output sections can be collapsed or expanded at once by clicking the button in the upper right corner.

Links

Use the 'jump-to' navigation feature by clicking the icon next to stream names for faster navigation.

Listeners	Talkers

Upon clicking the link, the application transitions to either the Listeners or Talkers view and the corresponding device is selected.

Listeners

The Listeners view facilitates routing between audio input streams (left) and channel groups (top). Individual routing is indicated by squares in the matrix.

Input streams and channel groups, can be expanded and collapsed by clicking on channel groups or input streams.

Connect a Stream

To connect a stream, left-click the button next to the 'Connect streams (x left)' label. This option is available only if the device has remaining listener stream capabilities.

	Description
	Ability to connect an additional stream.
	No ability to connect an additional stream.

Connecting further streams fails despite available streams if the devices are not in the same Media Clock domain or do not use the same sampling rate. The background is explained in Talkers, listeners, streams, and channels.

By clicking the button, a flyout menu is opened to pick from streams available in the network.

Left-clicking the button next to a stream adds the stream but keeps the flyout menu open to add multiple streams. By clicking the row, this stream gets connected and the flyout is closed directly.

Input Stream Status

Connected input streams display the talker's name and connection status:

Icon	Description
	Network connection working correctly.
	Network connection not functioning correctly.

Disconnect a Stream

The disconnection of a stream is accomplished by left-clicking the button located in the top row of the respective stream followed by clicking the icon in the flyout menu.

Multiselection

Multiselection enables simultaneous modifications to multiple listener devices that share the same number of audio channels and streams.

To begin editing multiple listeners, the Ctrl key (Windows) or the ⌘ key (macOS) should be held while selecting devices on the left. Any changes made on the right side are applied to all selected devices.

If multiple devices with the same capabilities but different connected streams are selected, the difference is indicated.

Editing is not permitted in this state. However, streams may be removed to establish a common configuration for all devices.

If the connected streams match but the dynamic mapping differs, an orange outline highlights the matrix crosspoints.

When enlarged, differences in individual crosspoints are indicated by the icon. Modifications to the mapping may be applied in the same manner as previously described.

Quick-Select Groups

Listener multiselections can be saved and recalled using quick-select groups. For details, see Quick-select groups.

Talkers

The Talkers view facilitates routing between channel groups (top) and output streams (right). It lists all available talkers in the AVB domain. Selecting a talker device on the left allows modifying output mappings if supported by the device.

Presentation Time

Next to each audio output stream name, the presentation time of the selected audio stream can be adjusted by clicking the icon.

Presentation times that are no longer valid due to accumulated latency of connected listeners are grayed out and cannot be selected. The purpose of the presentation time is explained in Presentation time.

Devices

Device Identify

Some devices implement an identification feature that helps locating the device. Invoke device identification by right-clicking a device row and selecting 'Identify Physical Device (10s)'.

Sorting Devices

Sort devices by clicking on column headers (NAME, VENDOR & TYPE).
