The Broadcast audio and video features are being integrated into the icue and Elgato software by Corsair. You only need a compatible headset, microphone, and camera. You don't have to use the separate Nvidia Broadcast app for features like noise removal and virtual camera background because the integrations in iCue, Elgato Wave Link, and Elgato Camera Hub all work together.
Thanks to the integration of the Nvidia Broadcast, nearly every Corsair headset will be able to remove noise and echo. Elgato Face cam owners can easily enable a virtual background feature that eliminates the need for a green screen with video integration for Elgato's camera hub.
Nvidia Broadcast used to be known as RTX Voice
The Broadcast app is known for its ability to process audio and suppress background noise. You don't have to run the dedicated Broadcast app if you use the Corsair integrations. It is ideal for streamers who already use Elgato and Corsair hardware.
You can enable the Broadcast noise removal feature if you own an Elgato microphone that uses Wave Link. Virtual studio technology in Elgato Wave Link can be used to remove noise from individual audio channels. It is supported in a number of applications.
Corsair has a useful FAQ on the integration, which is in the latest iCue and Elgato software.
