Audio Interfaces
Livewire+ AES67 audio inputs for camera switching
Use microphone channels from an AES67-compatible studio through a supported receiving interface and audio driver. VRA monitors those inputs for camera switching. This requires an audio receive path; the Livewire LWRP control connection does not carry audio.
How Livewire+ AES67 and VRA work together.
The channel layout is recognised
VRA identifies supported RAVENNA, Merging, Digigram, Dante and RME device layouts rather than a generic device named AES67. Any compatible input can also be mapped channel by channel.
One trigger per channel
VRA can build a bank of triggers from the detected layout, already tied to the correct device and channel. You name the microphones and assign the actions.
Meters show the real input
Check each microphone's input level and peak hold, then calibrate its trigger for the room. This helps you set when speech should cause a camera change.
Switch cameras from microphone activity
When a microphone passes its configured threshold, it can select a camera, recall a PTZ angle or run a macro. The programme audio stays on the console and is never mixed by VRA.
How to set it up.
Requirements
- The VRA Audio Manager app on a machine that can open the AES67 audio device.
- the AES67-compatible interface and its Windows driver installed and working in the operating system.
- The console or audio network already routed to the receive channels. VRA listens to those channels; it does not create or change the audio routes.
Install and configure the AES67-compatible interface and its Windows driver on the Audio Manager machine, then route the studio microphone channels into it.
Start the VRA Audio Manager app and confirm that the channels appear in the studio's audio device list.
Open Audio Triggers in VRA Cloud. Use the detected AES67 layout to create one trigger per channel, then name each trigger for its microphone.
Open the Audio Matrix, check which trigger listens to which channel, run the calibration pass and test every microphone before using automatic switching on air.
Livewire+ AES67 questions
Does VRA route or mix AES67 audio? +
No. Your console and audio network keep doing the routing and mixing. VRA only listens to the operating-system input channels so it can detect which microphone is active.
How does VRA find AES67? +
VRA identifies supported RAVENNA, Merging, Digigram, Dante and RME device layouts rather than a generic device named AES67. Any compatible input can also be mapped channel by channel.
What happens after the channels appear? +
Create or bulk-create an Audio Trigger for each microphone, check the channel mapping in the Audio Matrix, calibrate the gate and assign the camera or macro that should fire.
Can I still configure the channels by hand? +
Yes. Device recognition is a shortcut, not a requirement. You can select a compatible input device and map its channels manually. Test that Audio Manager can open the driver and receive each microphone.

About Livewire+ AES67.
AES67 is an interoperability standard for high-performance audio over IP. VRA does not open an AES67 stream by itself. It reads the receive channels exposed by the compatible interface or software driver already used in the studio.
Visual Radio Assist does not mix or route this audio. Audio Manager listens to the channels that AES67 exposes to the operating system and turns their activity into camera, macro and playout commands.
