Routing audio and streams

Learn how to manage device subscriptions and create audio routings for Dante and Ravenna protocols. Depending on the system's active AoIP setting, you must handle the routing differently. The two sections below explain what is the process and their differences.

Ravenna

This process is split into stream management and audio input routing for Ravenna and AES67 operations.

Stream discovery

Before routing streams to audio inputs, you must subscribe to them. This is done through the Streams section on the Routing page.

There are two methods for discovering and subscribing to streams. They are both available through the Discover Streams button.

• Automatic discovery: if the HOLOPLOT Controller is a part of the same network as the audio streams, we can automatically discover Audio Streams based on mDNS and SAP announcements.

• Manual subscription: if no streams are discovered automatically, you can manually input an SDP (Stream Definition Protocol) generated by your audio device.

Automatic Stream Discovery

Stream management

You can unroute Inputs or unsubscribe streams using the contextual menu available in each stream. When unsubscribing to a stream, its existing routings will automatically be deleted.

Supported streams

HOLOPLOT Audio Modules complies with ST 2110-30 stream formats, specifically under the following specifications:

• Linear 24-bit PCM encoding (L24)

• 48 kHz sampling frequency (media clock)

We recommend using Level A for AES67 compliance among the three SMPTE Conformance Levels.

Levels	Description
A (AES67 compliance)	1-8 channels Packet times of 1ms
B	1-8 Channels Packet times of 125μs
C	1-64 Channels Packet times of 125μs

How to route Streams to Audio Inputs

In the Routing view, you can connect channels from the subscribed streams to desired audio inputs. Some advice for working with this view:

• You can access more information about the beams connected to by simply clicking the name in the Audio Inputs header. This will present you with a panel listing all presets with beams connected to the audio input.

• You can perform a diagonal routing by holding Ctrl (Windows) and Cmd ⌘ (Mac OS) while hovering over the routing matrix.

• To view the number of active connections, toggle the switch (show # of connections) at the top of the routing matrix.

Dante

When working with Dante-configured systems, the process is split between Dante Controller and HOLOPLOT Control.

Connecting dante devices to Audio Modules in Dante Controller

You can use Dante's Multicast Flows to connect your source devices to our Audio Modules in Dante Controller. Ensure the Multicast Flows are connected to all HOLOPLOT Audio Modules in your system.

Connecting Dante channels to audio inputs in HOLOPLOT Control

The process is similar to the one used for routing in Ravenna. You will see a single Dante Stream that includes all 256 Dante channels. From there, you can proceed to route the audio inputs as desired.

This approach allows for quick channel mapping changes in one place, eliminating the need for constant back-and-forth in complex multicast routing for multiple modules.
