Audio Interfaces
RAVENNA audio-triggered camera switching
Use your RAVENNA audio inputs to switch radio studio cameras when someone speaks. VRA Audio Manager monitors each microphone through a compatible audio driver, while your console keeps mixing the programme.
How RAVENNA and VRA work together.
The channel layout is recognised
VRA recognises RAVENNA Receive WDM pairs and the RAVENNA ASIO or Merging Audio Device drivers. Select the detected layout that matches how the studio routes its channels.
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 RAVENNA audio device.
- the RAVENNA or Merging audio 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 RAVENNA or Merging audio 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 RAVENNA 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.
RAVENNA questions
Does VRA route or mix RAVENNA 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 RAVENNA? +
VRA recognises RAVENNA Receive WDM pairs and the RAVENNA ASIO or Merging Audio Device drivers. Select the detected layout that matches how the studio routes its channels.
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 RAVENNA.
RAVENNA carries real-time audio over an IP network. A RAVENNA or Merging driver presents receive channels to Windows, where Audio Manager can listen to each studio microphone separately.
Visual Radio Assist does not mix or route this audio. Audio Manager listens to the channels that RAVENNA exposes to the operating system and turns their activity into camera, macro and playout commands.
